SOURCE: Remote key will not open


Your key may have lost its initialization. To reinitialize a key you new to take all of your remote key and print these instructions out and jump in the car. Make sure all of the doors, hood, windows, trunk and sunroof are closed. Them make sure all of the doors are unlocked. Turn the key to just the radio position (just until the radio turns and as well as the airbag light), if the service engine soon light comes on you have turned the key too far, and you need to start over. Once you turn to the radio position turn the key off and pull the key out. Press and hold the unlock button of the remote, then press the lock button three times. At this point the locks of the car should lock and unlock. If this does not happen you need to start over. If you have another key you should initialize that key by starting at the the point of pressing and holding the unlock button, until the doors lock and unlock. Then the key should work again. The entire process with two key should take no more than 30 seconds. You may have to practice this a few times to get it right. I would suggest bringing the instructions with you in the car while doing them. If you have to start over to try again take the key out of the ignition open and close the drivers door and start from the beginning.

You body style car has the tendency to pop the fuel door lock actuator fuse. To see if the fuse is blown you can simply lock the car and see if the fuel door locks respectively. Then see if it also unlocks. If it works you should have no problems. If the lock does not work you will not be able to initialize the key/s, because the fuse is also the same fuse for the antenna that gets the signal form the key. Find the fuse that is blown in the right hand side trunk compartment and replace it. You can do one of two things to make sure that it does not pop again. Unplug the fuel door lock actuator, or replace the the actuator. The actuator is located at the end of the little green emergency release cable also in the right side of the trunk compartment. They have change the fuse number through certain model years so I do not remember which fuse it is but i think it is a 7.5 amp fuse. Once the fuse pops the keys will have to be reinitialized once the fuse is replaced.

Another reason why you key does not work is because is just flat out broken, and unfortunately this is the most costliest repair as the dealer is the only one who can get you another one. If you have done all of the above steps and you key still does not work then your key is probably bad, but I would not guarantee it. It may have to be checked out. If you have two keys and one will initialized and the other will not then I am pretty sure you have a bad key. Just remember to try to read, and try the initializing steps a few times as it may not work the 1st time.
One more update that might be causing this problem :-

Fuse 57 fails, and causes this problem. I would start with checking this fuse.
BMW has a bulletin for this, which involves replacing the 15a mini fuse with a 20A fuse to prevent failure due to current spikes in the system.

The fuse box is behind the removable panel in the glove box. The fuse card with diagram should be stored in the back of this panel.
Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

SOURCE: keyless entry won't work

I have a 1999 BMW E46 I have had a problem with the keyless entry myself. I brought the car to BMW Dealer and they told me that my Lock had an issue and that they need to repair some wiring wich would cost me $1,023.98 to find out that it was a fuse that burned out. I have replaced the 5 amp fuse with another one but it burned the fuse again so I put a 10 amp fuse and i have not had a problems since. In my car is fuse # 54 if Im not mistaken. But waht you can do is open the fuse box which is located in your glove compartment look for a diagram that shows you which fuse is where it will give you a fuse name a number where the fuse is located and how many amps fuse it is.

SOURCE: My keyless entry doesn't work,

my Volvo acts like that if someone sets off the alarm. You probably already tried this, but just use the key in the doorlock if you can, then get in and drive it normally. lock and unlock the doors some like you might normally, while the key is in the ignition (using the door buttons inside) and that should reset the alarm... good luck!

Can't program Second remote to my Ford Explorer 99

reading your post you mention to "open and close switch"..not sure what refering to...these are the instructions from your vehicles service manual...good luck!

Programming NOTE: All keyless entry remote transmitters (15K601) are programmable and must be set at the same time.
NOTE: To program (or reprogram) the keyless entry remote transmitters into the RAP module, perform the following steps:
  1. Make sure that the anti-theft system is not armed or triggered.
  1. Turn the ignition switch (11572) from OFF to RUN eight times within ten seconds, ending in RUN. If the RAP module has successfully entered program mode, it will lock and then unlock all doors.
  1. Press any button on a keyless entry remote transmitter, and the doors will lock and then unlock to confirm that each keyless entry remote transmitter has been programmed.
  1. If the door locks do not respond for any keyless entry remote transmitter, wait several seconds and press the button again. If the door locks still fail to respond, refer to Diagnosis and Testing.
  1. Turn the ignition switch to the OFF position, or wait up to 20 seconds after step 2, to exit program mode. If a keyless entry remote transmitter has been programmed (or reprogrammed), the RAP module will lock and unlock all doors one last time to confirm.

Remote keyless entry

I assume you are talking about the key fob. First, pry it open and change the battery. Watch which way the + goes.
If your key fob works, and the battery did not fix it, try reprogramming following the instrcutions in the owner manual. May need both fobs present at the same time.
Note; This is different than programming the anti-theft key.

Keyless entry on honda civic 2006 not working

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.
