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.

At first,it seems your remote has lost its code.Try using your other keys.
Do you have all doors+hood properly closed?Does your key actually turn in door lock!

2004 buick rendezvous wont go in to program mode for remote programing
Transmitter Programming
Important: All transmitters which are to be recognized by the remote control door lock receiver (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to 4 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.
Install a scan tool.
Use the scan tool in order to access programming: Vehicle Control System/Computer Integrating System/Module Setup/BCM/Program Key Fobs.
Press the START soft key on the scan tool.
Important: The scan tool must stay connected until all of the transmitters are programmed.
Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of 5-10 seconds, the scan tool will indicate that the transmitter is programmed.
Repeat the previous step in order to program up to 4 transmitters.
Remove the scan tool.
Operate the transmitter functions in order to verify correct system operation.

2008 cadillac cts key fob not working
Testing would need to be done , scan tool hooked up checking DTC'S - diagnostic trouble codes . View data etc...
Keyless Entry System Description and Operation - Active
The keyless entry system is a vehicle entry device. The keyless entry system is used in conjunction with the door locks to unlock the vehicle. Keyless entry will lock/unlock a door or open the rear compartment lid when a corresponding button on the keyless entry transmitter is pressed. This is accomplished by the transmitter sending a radio frequency to the remote control door lock receiver (RCDLR). The RCDLR interprets the signal and activates the requested function via a serial data message. A low transmitter battery or radio frequency (RF) interference from aftermarket devices, such as 2-way radios, power inverters, computers, etc., may cause a system malfunction. High RF traffic areas, such as gas stations that use pay-at-the-pump RF transponders, may also cause interference that could lead to a malfunction. Keyless entry allows you to operate the following features:
• Door lock/unlock
• Rear compartment lid release
• Illuminated entry lamps
• Panic alarm/Vehicle locator
• Remote vehicle start

Your best bet , take it to a qualified repair shop . Dealer
