Hi, You can not do it yourself. Take it to the dealer and they will reprogram it for you and give you a new key. If the remote has a week battery it won't work either. Replace battery Good luck
4 things to consider.
1. Does your key fob transmitter need a new battery.
Replace battery.
2. The remote module is faulty.
Replace module.
3. The lock actuators may have worn out.
Replace actuators (it may only be 1 or 2 of them)
4. (Most likely) All the associated wiring may need checking for earthing problems and /or breaks. The spade type connectors often rust inside the door.
(But if you can, pull each lock up by hand to see if its smooth. If you have to put real effort in to pull it out then the actuator is the problem)
Will the switch on the door lock or unlock the doors, if so check the battery in your remote, it may be dead. Remove the key remote from your keychain and there is a slot in the end of the remote that will open it up so you can gain access to your battery. Pay close attention to the way the battery is installed before removing it. Replace the battery and try the door locks again. If they work, then you have solved the problem. If not, you have an electrical problem that you will have to trace down. From the information you have given, this is all I can tell you without seeing the car for myself.
I wish you luck, I hope this helps you find the problem.
You need to replace the lock actuator in the doors that are not locking/unlocking with the door switch/remote. If the remote works for most of the doors then it is fine. The actuator is what moves the lock when it gets the signal from the remote or door switch to move it. Good luck
The message stands for Remote Function Actuation (RFA) battery low.
This in more simple terms means that the battery in your remote for the
door locks is getting low and should be replaced soon.
There is a battery in the remote.If the battery gets old the remote will stop working.Replace the battery and check.Also if your battery is new but still the problem is there then,try to open the garage door by keeping less distance between remote as well as the garage door.Also there is a sensor in the garage door.If that sensor is not functioning then this can be one issue.In some cases the internal remote circuit gets short,in that case the remote needs replacement.But does the garage door sensor light shows any sign of getting connection from remote when you press the remote button.Open the door and try to close the door with remote and check.As per the problem,in most cases its weak battery related problem,and replacing the battery solves the problem.You can try all the possibilities and see which one helps.Thanks.Helpmech.
The only way to program a transmitter is with a scan tool.If you have more than one transmitter then you have to program them both or if you program one the other one will not work.They do this at the dealership but if you are just replacing the batteries then you should not have to program the remotes.Hope this helps.Good luck.
try replacing the battery in the remote and then have the alarm program re flashed if the new battery in the remote doesn't fix the problem.Unfortunately I believe this has to be done at the caddy dealer.good luck
