Are you trying to leave the truck run and locked with keys/remote in hand? if so,you should have to push the start button on remote then take keys out then exit the truck without hitting the brake pedal and lock the doors. and if you can't do this then your sec. by-pass mod. or wire should be looked at

Electrical • Vehicle Theft Security • Description Report a problem with this article



The Vehicle Theft Security System (VTSS) is designed to protect against whole vehicle theft. The system monitors vehicle doors, and ignition action for unauthorized operation.
The alarm activates:
  • Sounding of the horn
  • Flashing of the headlamps/park/tail lamps
  • An engine kill feature (with SKIS)


The Sentry Key Immobilizer System (SKIS) is designed to provide passive protection against unauthorized vehicle use by disabling the engine, after two (2) seconds of running, whenever an invalid key is used to start the vehicle. The SKIS is active whenever the ignition is on and does not require any customer intervention. The primary components of the system are the Sentry Key Remote Entry Module (SKREEM), Sentry Key (ignition key with a transponder molded into the head), indicator light, Body Control Module (BCM), and the Next Generation Controller (NGC). The SKREEM is mounted on the ignition switch/lock cylinder assembly with the molded, integral antenna mounted around the ignition housing. The indicator light, is located instrument panel switch pod, just to the right of the instrument cluster.
Electrical • Vehicle Theft Security • Operation Report a problem with this article



Upon failure of proper SKREEM communication to the Next Generation Controller (NGC), the NGC will shut off fuel after two seconds of run time. The engine will not re-crank on the key cycle that the failure occurred, a full key down sequence must be performed for the engine to crank again. After six consecutive fuel shut-offs, the engine will no longer crank on subsequent key cycles. The failure must be corrected and a valid communication process between the SKREEM and the NGC must occur for the engine to crank and start again.
The electronics for the VTSS are part of the Body Control Module (BCM). The system is armed when the vehicle is locked using the:
  • Power door lock switches (with any door ajar)
  • Remote Keyless Entry transmitter.
  • Door Cylinder Lock Switches.
For vehicles equipped with SKIS, the doors do not have to be locked to enable the fuel shut off feature.
After the vehicle is locked and the last door is closed, the set LED indicator in the instrument panel switch pod will flash quickly for 16 seconds, indicating that arming is in progress. If no monitored systems are activated during this period, the system will arm and the LED will flash at a .5 Hertz (Hz) rate. If the liftgate is open, the LED will change its flash rate.
This indicates that the system is armed. If fault is detected on the driver key cylinder input, the indicator LED will remain solid during the arming process, although the system will still arm. If the indicator LED does not illuminate at all upon door closing it indicates that the system is not arming.
Passive disarming occurs upon normal vehicle entry by unlocking either door with the ignition key/remote transmitter. This disarming will also halt the alarm once it has been activated.
A tamper alert exists to notify the driver that the VTSS had been activated. This alert consists of 3 horn pulses when the vehicle is disarmed.
NOTE: The VTSS will not arm by pushing down the door lock mechanism. This will manually override the system.
If the VTSS is triggered, the horn will pulse, headlamps/marker lamps will flash, and the VTSS warning lamp will flash. If BCM determines the threat to be false and the VTSS is not triggered again, the system will shut down and rearm itself after three minutes. If a trigger is still active, the alarm will continue for an additional 15 minutes without the horn. The VTSS monitors the passenger compartment.
NOTE: System will not arm if passenger compartment is not secure.


  1. With the key removed from the ignition lock and any door open (excluding liftgate), actuate one of the following:
  • Power door lock button to LOCK,
  • Key fob LOCK button
  • Driver door lock key cylinder to locked position.
  • Close all opened doors. Liftgate can remain open.
  • After the last door is closed, an arming time-out period of sixteen seconds will start, then the VTSS will become armed.


    Actuating the key fob transmitter LOCK button, key locking the front doors with the doors closed and the ignition locked will begin the arming time-out period. If method A, 16 second time-out sequence was in process when method B was actuated, the 16 second time-out will restart from the time of the second actuation.
    If the security lamp does not illuminate at all upon final door closure, it indicates that the system is not arming.
    The current VTSS status armed or disarmed shall be maintained in memory to prevent battery disconnects from disarming the system.


    After the VTSS is armed, the following actions will trigger the alarm:
    • Opening any door (excluding liftgate).
    • Turning the ignition to the RUN position.
  • NOTE: When the VTSS is ARMED, the interior power door lock switch ?UNLOCK? will be disabled until the vehicle is disarmed.
    CAUTION: The VTSS indicator LED will trigger and engine will continue to run if the vehicle is equipped with SKIS and the proper key is used to start the vehicle. This condition will occur if the VTSS has been triggered. If valid key is used, VTSS will disarm.


    This vehicle theft security system feature allows you lock all the doors with the key by using the drivers door lock cylinder.
    All vehicle doors and liftgate are locked with the first turn of the key to the LOCK position from the drivers door. A double activation feature of central unlocking requires you to turn the key in the door lock cylinder to the unlock position two times within two seconds to UNLOCK all vehicle doors at once.
    The first turn of the key in the door lock cylinder will disarm the system (the driver door cylinder lock switch connected to the back of the driver door lock cylinder) and unlock your drivers door. The second actuation within two seconds will then unlock all doors and the liftgate.


    The SKIS includes keys from the factory which are pre-programmed. Each SKIM will recognize a maximum of eight Sentry Keys. If the customer would like to own additional keys other than those provided with the vehicle, they can be purchased from any authorized dealer. These keys must be programmed to the SKREEM on the vehicle in order for the system to recognize them as valid keys. This can be done by the dealer with a DRB III® scan tool or by a customer if this feature is available in their market and they have two (2) valid keys already available to them. The SKIS performs a self-test each time the ignition switch is turned to the ON position and will store Diagnostic Trouble Codes (DTC's) if a system malfunction is detected. The SKIS can be diagnosed and any stored DTC's can be retrieved using a DRB III® scan tool as described in the appropriate Body Diagnostic Procedures manual.
    With the light being on there is a code stored in the computer that controls anti-theft , Your best bet would be to take your vehicle to the dealer !

    Food particles left on the dishes suddenly !!!!!!!!!

    well this answer takes the cake, for about 3 months I've had problems with my dishwasher leaving "grit" on my dishes. After taking the inside drain area apart of my dishwasher, running a qt of CLR, gallon of vinegar, and any other product that someone mentioned or I saw in the store, THIS IS THE ANSWER TO THE PROBLEM.

    There are 2 screws at the top of the dishwasher that hold it in place under the counter, well when the builder installed it, they only put 1 screw in. Hence the dishwasher after 6 years got pushed back ever so slightly on 1 side and obviously was "pinching" the drain hose. Pulled it forward, put a screw in, to lock it in place and it appear to be working like new.

    I am also one that thought that the upper arm was getting water, well the upper arm rotates alternately with the bottom and its doing its job as well. Good luck everyone - Jo. Calgary, Alberta "Happy Stampeding"

    How do you reset the alarm system on a 98 olds silhouette after it triggers without the remote entry

    Theft Deterrent Arm/Disarm Modes
    Important: Although mode 2 provides increased security, the content theft deterrent system disarms only by pressing unlock on the keyless entry transmitter. This can pose a problem if the keyless entry transmitter is damaged, lost, or inoperative for any reason while you attempt to disarm the content theft deterrent system.
    Mode 1: The system arms when you lock the doors with the keyless entry transmitter. The system disarms when you unlock the left front, right front, or liftgate door with the key or the keyless entry transmitter. The system does not arm when you lock the doors with a power door lock switch.

    Mode 2: The system arms when you lock the doors with the keyless entry transmitter. The system disarms when you unlock the doors with the keyless entry transmitter. The system does not disarm when you unlock the doors with the key.

    Mode 3: The system arms when you lock the doors using a power door lock switch or the keyless entry transmitter. The system disarms when you unlock the left front, right front, or liftgate door with the key or the keyless entry transmitter.
    Changing the Feature Customization Modes
    1. Turn off the IP dimmer switch.
    2. Turn the ignition switch to the LOCK position.
    3. Remove the BCM PRGRM fuse.
    4. Turn the ignition switch to the ACC position. The BCM flashes the fasten belts indicator and sounds the chime 4 times, which indicates that BCM type 4 is installed on the vehicle. At this point, the BCM has entered the feature customization mode.
    5. In order to change the theft deterrent/shock sensor mode, turn the headlamp switch from OFF to PARK and back to OFF.
    6. The BCM flashes the fasten belts indicator and sounds the chime a number of times equivalent to the theft deterrent/shock sensor mode. A transition past mode 4 repeats the sequence starting with mode 1.
    7. Complete the following steps in order to change the theft deterrent arm/disarm mode:
    Insert the key in the left front, right front, or liftgate door lock cylinder.

    Rotate the key from the center to the unlock position.

    Press the horn button on the remote keyless entry transmitter.

    Count the number of chimes that you hear. The number of chimes tells you which mode you have set.

    Press the horn button again in order to change the mode. Continue to press the button until you hear the number of chimes that indicates the mode that you want.

    Turn the key back to the center position and remove the key from the door key cylinder.

    In order to exit and save the current feature customization modes use the following procedure:

    1. Turn the ignition switch to the LOCK position.
    2. Reinstall the BCM PRGRM fuse.
    If you are unable to change locking modes Theft Deterrent System Feature Customization Inoperative

    Have a DC25, I can not return the handle to the upright position. Nothing appears to be broken

    Occasionally, customers have problems locking their Dyson vacuum in the upright position. This is a minor problem common with the Dyson DC07 and DC14 series and can easily be fixed by the customer. This page will show how to fix this problem. Although we show a Dyson DC14 Animal on this page, these instructions will work on any Dyson vacuum in the DC07 and DC14 series.

    During shipping, moving parts on a Dyson vacuum can shift in position. One of these parts is a swinging arm in the base of the unit. This arm holds a removable elbow pipe in the vacuum's air passage. This arm can move out of the way so that you can clear out a blockage in the air passage. When this arm is out of position, the vacuum will not lock in the upright position. Fig. 1 Shows the base of a Dyson DC14 Animal locked upright. The red arrow points to the swinging arm. Fig. 2 shows the vacuum with the swing arm out of position. Since the swing arm is lower than it should be, it doesn't line up with the tab on the main body indicated by the red arrow.

    Lean the handle of your Dyson all the way back and locate the black button on the right side of the vacuum indicated by the red arrow in Fig. 3.. Press the button down and hold it to unlock the swing arm.

    While holding down the black button, pull the swinging arm (Shaded red in Fig. 4) all the way up. Fig. 5 shows the swinging arm in the correct position. Release the black button to lock the swing arm back in place.

    The vacuum can now lock in the upright position as shown in Fig. 6. Note how the tab on the swinging arm overlaps the tab on the main body..

    Cannot unlock the truck with the key,cylinder turns I think a part is missing off the clyinder

    Can you lock it with the key? If you can't then the arm or rod has come out of the lock mechanism. Ninty percent of all vehicles use plastic retainers to hold the rod and/or arm in place. They do wear out and break. You need to pull the interior door panel and look at the lock configuration to see if it is the rod or arm that has failed. You can get new clips from the dealer and some parts stores. If you break some of the clips that hold the door trim panel on, you can also get them new too. They are pretty standard for all ford products. Good luck, RAC
