Programming Electronic Door Lock Control System NOTE: The electronic door lock control processor (14B001) erases all previous keyless entry remote transmitter (15K601) from memory when the keyless entry remote transmitters are programmed or reprogrammed. The electronic door lock control processor can store up to four keyless entry remote transmitters in memory.

• To program (or reprogram) keyless entry remote transmitter into the electronic door lock control processor, perform the following steps:

1. Turn ignition switch to the RUN position and momentarily short the two terminals of the program connector taped to the wire assembly and located behind the glove compartment. All doors should lock and then unlock. Remove shorting pin.
   

1. Press any button on keyless entry remote transmitter. All doors should lock and then unlock to verify the keyless entry remote transmitter has been programmed. If door locks do not respond, press button again (up to three times maximum with the same keyless entry remote transmitter).
   

1. Repeat the above step to program additional keyless entry remote transmitters into the electronic door lock control processor (up to four keyless entry remote transmitters maximum).
   

1. Turn ignition switch OFF. All doors should lock and then unlock.
   

1. Check operation.
   

Try reprograming the remote does the panic still work check relays

I suggest you start by the basics as replacing the remote battery and then you can ask your local Ford dealer where the module is situated on the car as some of them could be very tricky to get to, ask about the price as well because it might be cheaper to get an aftermarket system fitted to your car.

The door lock actuators or 'solenoids' have failed. This seems to be pretty common on Windstars - I've just replaced a couple on my '02. (Ironically, the original batteries in the remote fobs are still going strong, they lasted longer than the actuators). You can buy third party replacement parts, the front door ones are 'handed' driver & passenger, but a common part will work for both sliding doors. I don't have instructions for removing the door panels, but search online - it's not tricky. The original actuators are riveted in place - you'll need to drill out these rivets. The new actuator can be held in place with a nut, bolt & couple of washers. Replacing these parts isn't too difficult - the first one took me about 1.5 hours, but once I knew what I was doing, the second one took about 0.5 hours. Good luck.

are you sure the battery is good in the remote? if so try putting the key in the driver door lock and locking and unlocking the doors three times in a row. if this dosent work i suggest taking it to an experienced lexus shop.

there are some contacts that touch when you close the door you should clean them off and your lock button will work more often use some steel whool to clean them off with...
good luck

check owners manual normally reprogramming procedure is listed in them. You might have to do all remotes over also.
