Not sure if the relay is for the door locks themselves, where the RKE control unit actuates the door lock motor.

There are a few options that can happen with this type install, depends on which after market system you are using.

The factory door locks ( without the factory RKE system ) the driver's side witch runs to the passenger side, and then to both door lock motors.

The polarity one direction is lock, the reverse polarity is unlock ( +DCV on 1 wire and ground on the other = lock, reverse the DC leads = unlock ).

The door lock diagrams for the 1998 MY F-150 :

A relay is just a way of a load AMP draw circuit ( the RKE control unit ) to operate a higher AMP draw device ( the door lock motors ). The ones I imagine that you would need are SPDT relays ( 5 pin ).
Do you have a URL to the install directions for the one you are working on ?
If so, post back a comment to this problem.
Thanks

2003 crown vic keyfob only works with ignition in run position .keyless entry and door locks work fine.even tried new keyfob.no change


The keyless entry system consists of the following components:
  • driver door module (DDM)
  • keyless entry transmitter
  • keyless entry keypad
The driver door module (DDM) receives inputs from the digital transmission range (TR) sensor, ignition switch, brake switch, window/door lock switches, lighting control module (LCM), keyless entry keypad switch and remote transmitter. The DDM outputs consists of keyless entry keypad switch illumination, power door lock actuators, luggage compartment release solenoid, horn relay, and lighting control module (LCM).
  • Battery junction box (BJB) fuses:
    • circuit breaker 7 (20A)
  • Central junction box (CJB)
    • 4 (10A)
    • 6 (15A)
    • 8 (25A)
    • 13 (5A)
  • Keyless entry keypad switch
  • Power door lock actuator
  • Luggage compartment release switch
  • Luggage compartment release solenoid
  • Connectors or connections
  • Wiring harness
  • If fuse's good have checked for DTC'S - diagnostic trouble codes .

Did you program the new key fob ?

Remote Transmitter Programming NOTE: All remote transmitters are programmable and must be set at the same time.
  1. Turn the key from OFF to RUN four times within three seconds, ending in RUN. The locks will then lock and unlock, confirming program mode has been entered.
  1. Press any button on each remote transmitter to be programmed. The doors will lock and unlock to confirm that each remote transmitter has been programmed.
  1. If additonal remote transmitters are to be programmed, repeat Step 3 within 7.5 seconds or steps 2 and 3 if more than 7.5 seconds have elapsed.
  1. To exit program mode, turn the ignition to START or wait 7.5 seconds.
  1. NOTE: Failure to wait at least 20 seconds will cause programming failures. Wait at least 20 seconds after turning the key to OFF or after the last remote transmitter has been programmed to activate a remote transmitter for testing or verification

Car won't start.Theft light blinks,clicking sound under hood and thumping like horn wants to go off.Seems like it's stuck in anti theft mode


anti theft light should blink every few seconds.

try disconnecting the battery for 15 minutes.

Anti-Theft-Perimeter The perimeter anti-theft system consists of the following components:
  • anti-theft indicator (THEFT)
  • remote anti-theft personality (RAP) module
  • hood switch
  • keyless entry remote transmitter
  • deck lid ajar switch
NOTE: The remote entry features will not function when the ignition switch is in the RUN or ACC position.
Up to four keyless entry remote transmitters (15K601) can be programmed at one time.
The keyless entry remote transmitters :
  • Are programmable.
  • Must be set at the same time.
  • House four buttons.
  • House three buttons (Mexico Anti-Theft System only).
Programming
Refer to Section 501-14B.
Inputs and Outputs
The remote anti-theft personality (RAP) module receives input from the following components for anti-theft operation:
  • Hood switch.
  • Deck lid ajar switch.
  • Keyless entry remote transmitter.
  • Power door lock switches (LH and RH).
  • Door courtesy input.
The RAP module distributes output to the following for the anti-theft system:
  • Power door unlock relay.
  • Power door lock relay.
  • Liftgate unlock relay (Wagon)
  • Park lamps relay.
  • HORN relay.
  • Dome lamp.
  • THEFT indicator.
  • Deck lid release.
Arming
The anti-theft system can be armed if:
  • The ignition switch is in the OFF position.
  • The panic alarm is off.
  • All doors are closed.
NOTE: If a door is open, the anti-theft system is prearmed and waiting for all the doors to be closed. The THEFT indicator will remain illuminated for up to 30 minutes waiting for all the doors to be closed. If a door remains open after 30 minutes, the THEFT indicator will turn off and the system will return to a disarmed state. After all doors are closed and the 30 second prearm (continuous THEFT indicator illumination) is complete, the system is armed.
NOTE: If the theft LED does not flash after 30 seconds, check the LED FLASH PID to see if the feature is enabled.
The anti-theft system will be armed when the lock button on the keyless entry remote transmitter is pressed, all doors are closed and 30 seconds have elapsed.
When the system is armed, the THEFT indicator will flash quickly until the system is triggered or disarmed.
Disarming
NOTE: Using a key in a door lock cylinder to unlock is not a valid method of disarming the anti-theft system.
Untriggered System
NOTE: If the driver arms the system and remains in the vehicle, an untriggered system can be disarmed by turning the ignition switch to the ON position.
An untriggered alarm system can be disarmed by pressing the unlock button on the keyless entry remote transmitter.
Triggered System
NOTE: If the hood or trunk are open when the system is armed, it must be closed and opened again before it can trigger an alarm.
An armed anti-theft system can be triggered by the following conditions:
The deck lid door, liftgate, hood or any door is opened using a key, inside door handle, hood release, etc.
  • The keyless entry remote transmitter can activate a panic alarm which is similar to the anti-theft alarm, but does not cause the THEFT indicator to flash.
A triggered alarm system can be disarmed by:
  • Pressing the unlock or panic button on the keyless entry remote transmitter.
  • Turning the ignition switch to the ON position.
Alarm State When Battery Power Is Cycled
When the RAP module is supplied power the first time at the vehicle assembly plant, the system will be in the disarmed state. The RAP module will remember whether it is armed, disarmed or triggered in its non-volatile memory. When the battery positive cable is removed and then reconnected, the system will return to the state it was in just before the battery was disconnected. If the system is in any prearm state, then the system will return to a disarmed state when the battery is disconnected and then reconnected.

Diagnose keyless entry system of 1997 Cherokee


Before replacing any Relay. Try disconnecting the negative side of the battery for at least 2-minutes to de-energize the security system, re-setting itself. The reconnect the battery and try your security (and options) system again.
The only other big question that you will have to know: is this a factory installed security system or an aftermarket security system? This makes a difference in security systems, relays etc.

atxhonda is right. Your going to have to replace the stereo and an aft mkt stereo will be the cheapest by far, however you should know that 96-00 Civics keyless entry control unit is inside the factory unit and by replacing it with an aftermarket deck you will lose you factory keyless entry system. If you don't have or use honda factory keyless entry or maybe you have an aft mkt keyless entry installed than I would go with the aft mkt deck.

Keyless entry wont work 2002 chevy s10


The only way to program them is with a scan tool so you'll need to visit your local dealer to have it done. Here is how it is done.

  1. Install a scan tool.
  2. Use the scan tool in order to access programming: Vehicle Control System/Computer Integrating System/Module Setup/BCM/Program Key Fobs.
  3. Press the START soft key on the scan tool. Important: The scan tool must stay connected until all of the transmitters are programmed.
  4. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of 5-10 seconds, the scan tool will indicate that the transmitter is programmed.
  5. Repeat the previous step in order to program up to 4 transmitters.
  6. Remove the scan tool.
  7. Operate the transmitter functions in order to verify correct system operation.

Fuse or what


Your multifunction switch on the steering column controls your exterior lights. The GEM module controls the interior lights and other stuff. If bad, it would not blow fuses. WHich fuse blows?
Your Ford dealer might be familiar with this issue, so call the service dept and ask them and get a quote. It may be wiring.
reoprt back.

  • The high beams are inoperative
  • Circuitry.
  • Multifunction switch.
  • Go To Pinpoint Test C .


--------------------------------------------------------------
Principles of Operation
Generic Electronic Module (GEM) The generic electronic module (GEM) receives inputs from the following:
  • door ajar switches
  • liftgate ajar switch (wagon)
  • liftgate glass switch (wagon)
  • headlamp switch
  • keyless entry keypad switches
  • the powertrain control module (PCM) (vehicle speed signal)
  • ignition switch
  • remote keyless entry transmitter
The GEM uses these inputs to control the output to the battery saver relay and interior lamp relay. Both relays are integral to the central junction box (CJB) and cannot be accessed directly.
Interior Lighting Systems The GEM grounds the battery saver relay and interior lamp relay coils when any door ajar switch or the headlamp switch is closed. The interior lamp relay then supplies power to the interior lamp circuit. Vehicle speed must be less than 15 kph (9 mph) for the GEM to ground the interior lamp relay. The interior lamps will remain illuminated for a period of up to 25 seconds after all doors are closed or until the ignition is switched from the OFF position, or the GEM receives a vehicle speed signal. Actuating the interior lights from the headlamp switch will operate at any time.
Illuminated Entry Illuminated entry is activated when a keyless entry keypad switch provides ground on the GEM input or when the GEM receives an unlock signal from the remote keyless entry key fob. The GEM then provides ground to the battery saver and interior lamp relay coils. Illuminated entry is deactivated when the GEM receives a lock signal from the remote keyless entry key fob or if the GEM receives ground inputs from the keyless entry keypad switch lock code. Illuminated entry will also be deactivated when the GEM receives input voltage from the ignition switch.
Battery Saver The battery saver is activated when the GEM is not receiving voltage input from the ignition switch (off position). The GEM will then provide ground to the battery saver relay coil for a maximum of 30 minutes depending on the state of the interior lamp switch inputs to the GEM. The energized battery saver relay switches voltage to the demand lamp circuit and the interior lamp relay coil. After time-out, the GEM removes ground to the battery saver relay disabling the demand lamp circuit.
Puddle Lamps The puddle lamp relay operates reverse from the battery saver relay and the interior lamp relay. The puddle lamp relay coil receives voltage when the ignition switch is in the START or RUN position, which disables the circuit to the puddle lamps.
Inspection and Verification
  1. Verify the customer concern by operating the system.
  1. Visually inspect for obvious signs of mechanical and electrical damage.


Visual Inspection Chart Electrical
