I have a 2004 Nissan Merano and sometimes when I turn my alarm off and go to start it, it will not start and the red car with the key on it flashes please help!!!


Well, ill assume that since you have an l.e.d. your alarm is aftermarket. My guess is your alarm is in "passive arming mode". That means its arming. Itself. Some alarm dont fully arm in that mode, usually just the starter kill and led engages. That mode (sometimes happens) and can be changed via your remote. Hope that helps.

What is the valet button located inside of glove compartment used for


It is used for programing the alarm, it is used to disarm the alarm without the remote, [in case remote is damaged] and it is used to put alarm system into valet mode, [service mode] valet mode is only really needed if the alarm has been programed for passive arming, [alarm arms itself].

Your main use for the valet switch, [if programed for active arming instead of passive arming] is to have a way to disarm the alarm if the remote does not work.

My 2001 tahoe alarm keeps "auto" arming itself after about 30 seconds. How do I stop it from "auto" arming? Its driving me crazy


this alarm works with the remote and the key, if you lock with the key it arms if you lock with remote it arms,when you unlock it it should disarm, if your having a problem with it not working try the pass/side lock with key, that should shut it down but if it keeps rearming without locking doors then it may be aftermarket, also in your manualy it will show you that some factory alarms are also self arming this is programed through the cluster, using the buttons on the dash, you scroll through the options and shut off auto arming, this is done the same way you scroll for mileage or trip time or oil change life. hope this helps.

Starting System
The function of the starting system is to crank the engine at a speed fast enough to allow the engine to start. Heavy cables, connectors and switches are used in the system because of the large currents required.
The starting system consists of a gear reduced starter motor, battery, remote control switch (ignition switch) and relay.
Vehicles equipped with automatic transaxle have a transmission range sensor attached to the circuit which prevents operation of the starter motor unless NEUTRAL or PARK are selected.
Vehicles equipped with a manual transaxle have a start inhibit switch in the starter control circuit, which prevents operation of the starter motor unless the clutch pedal is in the applied position.
------------------------------------------------------------------------------
The anti - theft protection system provides protection from unauthorized entry into the passenger compartment.
The system is controlled by an anti - theft alarm control. When armed, unauthorized entry into the vehicle is detected by lamp switches.
Once triggered, the system flashes the headlamps, the parking lamps, the alarm indicator, and sounds the horn. In addition, the starter circuit is disabled to prevent starting the vehicle until the system is disarmed.
System Arming
The system will be armed by the remote entry transmitter when the following input sequence is followed:
  1. Turn the ignition switch off and remove the key.
  1. Close all doors (unlocked).
  1. Press the LOCK button on a transmitter to lock doors. Alarm warning lamp will turn on.
  1. Wait for the anti - theft warning lamp to turn off.
The system will also be armed when the following input sequence is followed:
  1. Turn the ignition switch off and remove the key.
  1. Open a door. Alarm warning lamp will flash.
  1. Lock doors with power door switches. Alarm warning lamp will now glow steadily.
  1. Close all doors.
  1. Wait for the anti - theft warning lamp to turn off.
Opening any door will activate the alarm after the alarm is armed.
Disarming an Untriggered System
The system can be disarmed by performing one of the following procedures.
  • Driver or RH front door is unlocked with a key.
  • Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.
  • If remaining in the vehicle, turn the ignition switch to ON or ACC position.
System Triggering
The armed alarm system will be triggered if any door is opened without using a key or a remote entry transmitter to unlock the door first.
Disarming a Triggered System
Carry out either of the following steps will disarm the triggered alarm system.
  • Driver or RH front door is unlocked with a key.
  • Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.
Two minutes and 45 seconds after the system has been triggered, the horns and exterior lamps will shut off automatically. The system will then reset to an armed state and will trigger again if another intrusion occurs.
--------------------------------------------------------------------
Passive Anti-Theft System (PATS)
The Passive Anti-Theft System (PATS), known as SecuriLock, is fully passive in operation and requires no special procedures by the driver to arm or disarm the system. It is invisible to normal scrutiny and is operated by a transponder within the key body. This communicates with the module through a transceiver mounted around the ignition switch lock barrel.
The PATS functionality is incorporated within the powertrain control module.
PATS keys contain an electronic device inside, and are physically larger than a non-PATS key.
The transponder code reading is carried out when the key is inserted into the ignition lock barrel, and turned from position 0' to position II' or III' to crank the engine. If the PCM receives the correct code signal, the engine will start. Should the code received not be recognized, the engine will not crank as the PATS is still armed and the engine immobilized.
Anti-Theft Indicator
Whenever the ignition is switched on the anti-theft indicator will remain on for three seconds while the system carries out an initial ignition key-read.
The anti-theft indicator will flash rapidly for three seconds to indicate the PATS has immobilized the vehicle.
For additional information on the PATS fault codes, refer to the Diagnosis and Testing section.

Locking mechanism is broken on driver's door.


If the valet key is not programmed to the Immobilzer system, it should start the car, but it will shut off. This is only if the car has an Immobilizer system. If your locksmith unlocked the car without the door key, then use the key to unlock and disarm the alarm in the door. If you triggered the alarm, the starter will be disabled till a unlock signal from a remote or the door is actually unlocked with a key. If that cannot be done, your only solution right now is to tow it to the dealership and have them make a master key and check the door locks for proper lock/unlock commands so the alarm will arm and disarm correctly.

Replaced the alternator, now anti theft won't disable


The ignition lock anti-theft switch (19A438) detects if the ignition key cylinder is broken or "slam pulled" during a theft. The ignition lock anti-theft switch is always monitored by the remote anti-theft personality (RAP) module. This allows the alarm system to be triggered in the case that the ignition lock anti-theft switch detects tampering of the ignition key cylinder (even in the event that the alarm is not active at the time).
Refer to the Section 501-14B for more details on the keyless entry remote transmitter (15K601).
The door open warning lamp switch (14018) communicates to the RAP module through the generic electronic module (GEM). This input to the RAP will cause the anti-theft alarm to be sounded if the anti-theft alarm was armed.
The door disarm switches are assembled into both LH and RH lock sets. The door disarm switch must be triggered before the mechanical lock unlocks. This is to prevent the anti-theft alarm from activating when it should have been disarmed.
The RAP module controls the anti-theft system and is the brains of the keyless entry system. The RAP module communicates with the GEM to request that the interior lights be turned ON/OFF with use of the keyless entry remote transmitter, and the GEM communicates to the RAP to inform when the door is opened. Refer to Section 418-00 for inter-module communication.
The RAP module has three wire connectors attached to it:
  • The antenna for the keyless entry remote transmitter.
  • 26 circuit connector (C256).
  • 22 circuit connector (C257).
In addition to the perimeter alarm that uses the door open warning lamp switch, the RAP module also uses the ignition lock anti-theft switch and the autolock/relock feature to prevent theft of the vehicle. For a full description of the autolock/relock system, refer to Section 501-14B .
The THEFT LED is found on the instrument panel between the tachometer scale and the needle pivot point. The LED is illuminated during prearming and flashes when armed or triggered.
Prearming and Arming the System
The system can be armed if:
  • The ignition is OFF.
  • The PANIC alarm is OFF.
  • All doors are closed.
There are two ways to prearm the system:
  • Press the LOCK button on the transmitter.
  • Open a door, press the power door lock button and close the door.
After 30 seconds the system will be armed and the theft indicator in the cluster will flash every two seconds.
Disarming an Untriggered System
An armed system will be disarmed with one of these valid actions:
  1. Pressing the UNLOCK button on the transmitter.
  1. Placing a key in the door and turning to UNLOCK.
  1. Turning the key to RUN or ACC.
The anti-theft alarm can be triggered by the following conditions:
  • The ignition cylinder is damaged with or without the RAP being armed.
  • A door is opened without disarming the armed RAP module.
The remote transmitter can activate a panic alarm which is similar to an anti-theft alarm, but does not deactivate the starter or cause the theft indicator to flash.
Disarming a Triggered System
If the system has been triggered, (the horn honks, the lights flash, and an external starter interrupt relay is engaged), the system can be disarmed by:
  1. Pressing the UNLOCK or PANIC button on the transmitter.
  1. Putting a key in the door and unlocking the door.
  1. Turning the ignition to RUN/ACC (Turning the key to RUN/ACC will not disarm an alarm that has been triggered by the ignition lock anti-theft switch.).
