Keyless Entry System Description and Operation - Passive
Passive keyless entry allows entry to a locked vehicle without pressing any buttons on the keyless entry transmitter. You must only have the transmitter with you. This passive system is also part of the vehicle starting system. It allows you to start and run the vehicle having only the transmitter as your key. The passive entry and starting system use low frequency antennas in 4 different areas on the vehicle to determine the location of the transmitter. When passively opening a locked door or the rear compartment lid, you must have a programmed transmitter with you in your pocket, purse, or briefcase. As a customer opens the door handle or presses rear compartment touch pad, the low frequency antenna sends out a challenge to the keyless entry transmitter. The transmitter must be in a one meter range of the door or rear compartment lid in order to receive the challenge. If the challenge is met, the transmitter will respond, allowing the door to be unlocked and opened. Passive entry allows you to operate the following features:
• Passive door unlock/unlatch
• Passive rear compartment lid release
• Illuminated entry lamps
• Vehicle starting
The keyless entry system has the following components:
• Keyless entry transmitters
• LH and RH door antennas (part of the door handle assembly)
• Rear compartment antenna
• Console passive antenna
• Console active antenna
• Instrument Panel Module (IPM)
• Rear Integration Module (RIM)
• Remote Control Door Lock Receiver (RCDLR)
• External RF Antenna (includes coax from RCDLR to back glass)
Remote Control Door Lock Receiver (RCDLR)
The RCDLR is a multi-function module which controls all the vehicles antennas for passive keyless entry functions. The RCDLR also acts as the receiver for active keyless entry and tire pressure monitoring (TPM) functions, as well as controlling all immobilizer functions.
The RCDLR's RF antenna is located in the back glass, and there is a coax cable connecting the glass antenna to the module located in the trunk.
Your best bet , take it to a qualified repair shop that has the factory Tech 2 scan tool or someother professional type scanner that can read • Rear Integration Module (RIM) DTC'S - diagnostic trouble codes .
I read where the keyless entry fob/remote can be used to open the windows remotely. Is it possible the button was inadvertently pushed while in your pocket/purse/etc?
i honestly am guessing,can you turn key to the left from vertical or right from vertical,if so one (left or right)is to lock trunk so you can give your keys to valet parkers....
should not be using fob buttons for entry or locking for emergency only .if keyless entry walk up to car with fob do not press any buttons see if door opens then walk away from car with fob about 20m then go back to car without fob and see if door locked if so all working fine .indicators will not flash if the above dont work take back to main dealer for diagnostics keys may need to be reprogrammed
To get inside the car .... Use the key in the lock cylinder, unlock the drivers door to get inside. You shouldn't have to reprogram the fob unless it or the keyless module was changed. There may be a blown fuse that supplies the keyless control module (check the owners manual for location). or wires that lead into the Drivers door may be damaged ... The keyless module is located inside the drivers door at the bottom behind the door panel ... do the unlock/lock and trunk release switches on the inside of the drivers door operate the locks and or trunk release? If so it is not the fuse ... and not the wires to it ... And it could be your BCM body control module, located in the dash board to right of your gas petal. Because the number entry keypad (code for that is on the inside of the right passenger trunk bracket arm) also doesn't work I assume it's not the key fobs themselves. Your 98 manual is correct for your car.
Same car same problem, but I found the plug w/two wires behind the glove box. It is on a brace on the left hand side, has a clip holding it there. Lift up on the clip and it slides off.
I jumpered those two wires, the door locks did not cycle as was in the instructions and remote still doesn't work.
Sounds to me like I'm missing power from somewhere, but where?
Hope you find your wires and they work for you.
