This is for the remote entry transmitter, not the PATS transponder chip in the key base.
Gather all the remote transmitters that you want the car RKE system to recognize.
Electronically unlock the doors, using one of the remotes that still works. if none work use the door lock switch on the interior of the drivers door press to open all door locks.
Turn the ignition switch from OFF to RUN 8 times within 10 seconds ending in RUN position. If the module successfully enters the program mode, it will lock and unlock all the doors.
Within 20 seconds press any button on all your remotes that you want to be able to access your car. Each remote will lock and unlock the doors as they are programmed into the memory. Turn the key to OFF to exit the programming mode.
This will eliminate anyone who has any other remotes that you do not want accessing the car.
do they work when using the master switch on the drivers door panel? if only the drivers door unlocks when pressing the button, it may be a personal setting change needed. in this case usually pushing the unlock button on the remote twice will then unlock all doors. if there is only one lock that doesn't work it is most likely the door lock actuator that is at fault or a broken wire in the door opening wiring harness of the door that the lock does not work on.
I really appreciate all the solutions that have been posted. The only concern that I have is that none of the solutions are referring to the 1987 Chrysler Fifth Ave. There is everything from Chev,GMC,Toyota and Honda. Does anyone have a solution for my Fifth Ave? Thanks Tony
it is not the actuators, try a different remote, you may have an issue with the car security system/body computer not functioning on the unlock driver door command, one press of remote is unlock driver door and 2 presses is unlock the other doors.
this is a problem that can appear after your car battery died, cause the car didn't reset propely, so taking the battery out and putting it back in or letting your car die again would do the trick. I tried a lot of reprogramming procedured for my remote key, none of them worked, what did the trick though was simply unlocking the doors via the all door unlock button on the passenger side door, so simple.
if you can here relays when unlocking/locking check for power at door lock actuators inside doors, if you have power on lock/unlock and good earth from connector actuators are faulty.
if no power on test light when operating check output from central door lock module while operating, none coming out of module then it might need replacing.
check 30Amp power fuse for main relay under bonnet (which goes to pin 8 white/blue on module)and 10Amp gauge fuse in cab(pin 1 blue/red on module),pin 15 is also power when relay is on(red/blue) with test light, and module/ actuators.
check outputs from module pin 3 & 4
that go to door locks
When you use your remote or insert your key in the Drivers Front door all the door locks should work at the same time by the door lock motors electrically. If you have to manually unlock the door because it will not lock or unlock by the lock motor, you need a door lock motor. The drivers and passengers front doors can unlocked with the key manually only. The rear doors you have to pull up the latch. If NONE of doors unlock electrically with the remote or drivers door lock, intermittently or all the time, you will need a Central Locking Electronic Control Module. Pressing the remote button you will hear the "beep", but no door locks will fire at all. If you have a few odd door locks not working intermittently or not at all, you will need a new door lock motor for each door lock that malfunctions. You can hear if the door locks are working electrically. Yes, they are common problem. If you can hear the door lock motor working but the door still doesn't unlock you need to take the door panel off and lubricate the door latch assembly and work the lock, loosening it up. This is common as well. Sometimes a bad door lock motor can blow the central locking fuse. You will notice it because it will take a second or two longer to lock and unlock compared to the others. If the door lock motors seem fine, install a the next step up in amperage fuse. (From 15 AMP to a 20 AMP)
This usually works.Lock the doors with the remote.Press lock twice sounding the alarm.Then press the unlock button twice.Your car should start now.If that doesnt work try this,Lock the car again with the remote once.Go over to the passenger side door and use the key to unlock the door then press in the door unlock all doors.Hopefully by now it worked.Now if none of these work your security probably malfunctioned and theres only two things that will work,One is disconnecting the battery for 5 mins then reconnecting.unlock doors.the start.If that doesnt work you'll have to take it to the dealer to get the security reset or replaced.The steps I have wrot you are the diagnostics to reset it.I hope these work for you and good luck.See ya had have a great day..
