SECTION 419-01A: Anti-Theft — Perimeter 2002 Explorer/Mountaineer Workshop Manual DESCRIPTION AND OPERATION Anti-Theft —Perimeter The perimeter anti-theft system consists of the following:

  • driver door disarm switch
  • vehicle security module
  • keyless entry remote transmitter
  • door ajar switches
  • liftgate ajar switch
  • liftgate glass ajar switch
  • hood ajar switch
------------------------------------------------------------------------------------
Anti-Theft —Passive The passive anti-theft system (PATS) contains the following components:
  • theft indicator
  • encoded ignition key
  • PATS transceiver module
  • powertrain control module (PCM)
  • standard corporate protocol (SCP) communication network
Principles of Operation
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code out of over 18 billion, billion combinations.
The passive anti-theft system (PATS), also known as SecuriLock ®, uses radio frequency identification technology to deter a drive-away theft. This system is known as SecuriLock® in North America, Safeguard® in the U.K., and PATS in Continental Europe. Passive means that it does not require any activity from the user.
The SecuriLock® System (PATS) is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. If equipped the remote start system must be removed before investigation of PATS-related, no-start issues.
Each encoded ignition key must be programmed into the vehicle's powertrain control (PCM) before it can be used to start the engine. There are special diagnostic repair procedures described in this section that must be carried out if a new encoded ignition key is necessary.
This system contains a new feature named Unlimited Key Mode. This feature allows a customer to program more than eight keys to the vehicle if they request it. Each vehicle in Unlimited Key Mode is set up with a special Unlimited Transponder Security Key. This allows all the customer vehicles to share the same keys, but no other keys from outside can be used to operate the vehicles. For an individual customer, any randomly selected Security Key is acceptable. Refer to Unlimited Key Mode Programming in Key Programming Switch State Control in this section.
The PATS transceiver module communicates with the encoded ignition key. The module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends data to the PCM.
The control functions are contained in the PCM. This module carries out all of the PATS functions, such as receiving the identification code from the encoded ignition key and controlling the engine enable. The PCM initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
All elements of the PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start.
The PATS uses a visual theft indicator. The indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS concern, this indicator will either flash rapidly or glow steadily when the ignition switch is turned to RUN or START. The PATS system also flashes the theft indicator every two seconds at ignition OFF to act as a visual deterrent.
The PATS will be activated and will disable the vehicle from starting if there is a:
  • incorrectly encoded ignition key
  • damaged encoded ignition key
  • unprogrammed key
  • non-encoded key (key has no electronics)
  • damaged wiring
  • damaged transceiver
  • damaged PCM
Inspection and Verification
  1. Verify the customer concern by operating the system.
  1. Visually inspect for obvious signs of mechanical and electrical damage.
-------------
Key Programming Using Two Programmed Keys NOTE: This procedure only works if two or more programmed ignition keys are available and it is desired to program additional key(s). If two keys are not available, follow the procedure in Key Programming Using Diagnostic Equipment in this section.
NOTE: PID SPARE_KY must be enabled for this procedure to operate. If this PID is not enabled, follow the security access procedure above and select SPARE KEY PROGRAMMING SWITCH: ENABLED.
NOTE: If the programming procedure is successful, the new key(s) will start the vehicle and the THEFT indicator will illuminate for approximately three seconds.
NOTE: If the programming procedure is not successful, the new key(s) will not start the vehicle and the THEFT indicator will flash. If the programming procedure was not successful leave the ignition switch in the RUN position for at least 30 seconds then repeat the key programming procedure from Step 1. If the failure repeats, refer to Diagnosis and Testing to review the DTCs and carry out pinpoint tests as necessary.
NOTE: A maximum of eight ignition keys can be programmed to a passive anti-theft system (PATS) equipped vehicle. If more are needed, refer to Key Programming Switch State Control in this section.
NOTE: If the steps are not carried out as described, the programming procedure will end.
NOTE: Ignition keys must have correct mechanical key cut for the vehicle and must be a PATS encoded key.
NOTE: If the vehicle is in unlimited key mode, this spare programming procedure still functions. Any two keys that can start the vehicle may be used to program in an additional unlimited key.
  1. Insert the first programmed ignition key into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for three seconds).
  1. Turn the ignition switch to OFF and remove the first key from the ignition lock cylinder.
  1. Within seconds of turning the ignition switch to OFF, insert the second programmed ignition key into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for three seconds).
  1. Turn the ignition switch to OFF and remove the second key from the ignition lock cylinder.
  1. Within 20 seconds of turning the ignition lock cylinder to OFF, insert the unprogrammed ignition key (new key) into the ignition lock cylinder and turn the ignition switch from OFF to RUN (attempt to start the vehicle).
  1. If it is desired to program additional key(s), repeat the key programming procedure from the beginning.
-------------------------------------------------------------------------------------
NOTE: The security access procedure is utilized to obtain passive anti-theft system (PATS) security access. PATS security access must be granted to erase ignition keys, enable/disable unlimited key mode, and enable/disable the spare key programming switch (PID SPARE_KEY). The security access procedure invokes an inherent 10 minute time delay prior to granting security access during which the diagnostic tool must remain connected to the vehicle. Once security access has been granted, a security access command menu is displayed which offers various command options. (For additional information, refer to Powertrain Control Module (PCM) Configuration Command Index).
NOTE: Once security access has been granted, multiple security access commands should be executed (if necessary) prior to exiting the command menu. This avoids the carrying out of an additional security access procedure and the associated 10 minute time delay.
  1. From the diagnostic tool Ford Service Function (FSF) card, enter PCM. Select SECURITY ACCESS. This procedure will take 10 minutes to carry out, during which the ignition switch must be in RUN and the diagnostic tool must be connected to the vehicle.
  1. After the 10 minute security access procedure has been completed, a new menu will be displayed with command options. Select only those functions necessary before exiting out of this menu. Once exited out of this menu, the security access procedure must be repeated again to carry out additional commands.

How to Program Keyless Entry Remotes in a Hyundai Sonata By Christian Killian, eHow Contributor
20Found This Helpful The keyless entry system in your Hyundai Sonata is part of the factory alarm system. If you have to replace a lost or damaged remote, reprogramming will be necessary. The remote is important because not only does it lock and unlock the doors, it also arms and disarms that factory alarm when you open or close your car doors. New remotes are available from any Hyundai dealer. While they will program it for you, you can do it yourself and save a programming fee.

Step 1: Locate the fuse panel under the dash on the driver's side of the car. Just below it is the control module for the factory alarm system. Open the cover on the alarm system control module and locate the memory switch inside.
(Kleophaus Livingston/Demand Media) Step 2: Verify that the switch is in the "Off" position; if it is not, switch it to the "Off" position. This is important for the system to understand what you want it to do when you move to the programming mode.

Step 3: Insert the key into the ignition of your Sonata and turn the key to the "On" position. Wait for 60 seconds, then move the memory switch inside the control module to "Set."
(Kleophaus Livingston/Demand Media) Step 4: Depress and hold the "Lock" button on your remote for one full minute. This allows the remote and the control module to communicate and sync. Release the "Lock" button and turn the memory switch in the control module back to the "Off" position.
(Kleophaus Livingston/Demand Media) Step 5: Turn the ignition switch to the "Off" position and test the remote by pressing the "Lock" or "Unlock" button, verifying that the doors do lock or unlock.

We've lost the key fob and need to use the spare key to enter car with out alarm sounding.


if you unlock the driver door before opening it with the key you can turn the alarm off. Also taking it to a electronics place and having a keyless entry system will bypass the factory alarm as long as you tell them to hook it up and in most cases its less than buying a new factory remote. Also if you dont lock the car with the lock button from the driver door before you close the door the alarm will not arm.

How do you know if the alarm is set?


If the alarm has no audible response, when set either by key less entry or manual activation, and you want to make sure it works, you can try opening the hood after locking the doors. That usually will set the alarm off

When I unlock my jeep the alarm goes off.


On some cars/trucks/SUV's, the alarm will go off if the car is unlocked with the key or if the door is opened (even from inside the car with the alarm set). Unlocking with a key does not always turn off a car alarm. Best advice, go to the dealership to get a new key-less entry remote, or get a new alarm installed with a remote to override the original alarm system.

Keyless entry stopped working on 05 cobalt now i have to unlock door with the key and when i do that the alarm goes off. Help


Lock all the doors from the inside (with all the doors closed), unlock your driver's door by manually lifting the lock, then press it back down after you are out - this will prevent the alarm from sounding when you use the key to unlock the door.
