Question about Volvo Cars & Trucks
Central locking normally by keyless entry, just stopped working, system seems to be locking and unlocking itself very fast, although the door will not open, when opening with the key the alarm goes off. Tried another remote, still the same. Remote batteries are in good condition.

Disconnect the battery from your car (negative cable only) overnight. Make sure you have your radio reset code before doing so.
Then reconnect after 10 hours, and make sure you have remote handy as alarm may go off. Then if that doesnt fix it, go to driver door, then insert master key, pull up on handle first all the way and hold it. Then turn the key slowly all the way so the doors unlock and continue turning the key. This will reset the central locking system as yours may have gotton stuck. then remove key let go of handle, open door and try to lock and unlock doors from switch inside car.
Then try remote. It should work, this is what the dealer will do and charge you about $350...if it doesnt work order a new remote b/c yours may have become damaged by liquid or dropping?
Have a great day,

SOURCE: BMW Keyless Entry not working
hi, to program the keys to the vehicle is quite simple
1) open the vehicle, sit inside and close the door
2) insert the key in the ignition and turn to position 1 so that just the air bag light illuminates
3) press and hold the unlock button on the key and remove the key from the ignition (do not release the unlock button)
4) while still holding the unlock button with the key removed press the lock button 3 times
5) release the unlock button on the remote and the door locks should lock and unlock if the proceedure has been carried out correctly
6) to program any other key(s) press and hold the unlock button on remote and again press the lock button 3 times but do not insert it into the ignition or turn the ignition on as done previous.
you may want to print these instructions and read them a few times before proceeding, if you muck up the process while programing keys, no harm will be done, you just have to start the process over. hope this is of some help, regards mark.

The keyless entry is designed to work with the doors closed (closed - not locked). If the door ajar sensor thinks the door is open the keyless entry is disabled. When you manually lock the door it might tighten the door just enough to activate the keyless entry. I would try slamming all the doors closed and then see if the keyless entry works. If it still wont work have the wiring checked on the front door lock.

There are two multiplex control units - one on the driver side and one onthe passenger side - which one did you unplug? The one on the driver side is the main "Brain" while the other one is the one that houses the keyless reciever. According to the service manual, any troubleshooting of this system must begin with the one on the driver side. It can get quite involved because Honda does not provide actual troubleshooting (symptom) charts, just descriptions of the electrical connectors and what conditions should be present at each conector pin under what system condition. (each pin has to be tested to determine what is malfunctioning) The system is not capable of outputting fault codes of any kind.
