Re: The remte control key is not responding with the car
Firstly, open your glove box and make sure Valet Mode is not enabled, if it is not, follow these steps.
Step 1: Open drivers door and leave open. Step 2: Lock and unlock the driver’s door using the power door lock switch on the door. Step 3: Insert key into the ignition. Step
4: Turn key to on position and return to off position. (IMPORTANT - use
ON position NOT ACC position). Do this 3 times within 10 seconds. Leave
key in the ignition. Step 5: Open and close the driver’s door 3 times. (Door should be left open after this step). Step 6: ECU should respond by locking and unlocking the doors. Step 7: Press any button on remote #1 twice. ECU responds by locking and unlocking the car doors. Step 8: Press any button on remote #2 (etc.) twice. Each time the ECU will respond by locking & unlocking the doors. Step
9: Remove the key from the ignition and the ECU will respond a final
time with a series of door locks and unlocks. You're done!

Do any of the other functions work? Since the battery came out, you may need to take it to a dealer and have the remote re-keyed to your specific car. If other functions do work, the circuit board in the remote might have been cracked across the traces to that particular button.
Press the button on the garage door opener (red, green, or yellow) until the led starts to blink and within 10 seconds or so, ( I think it's actually 30 seconds) press the GDO control button on the remote and the opener should capture the signal and respond to it from then on. Any remotes that were set to control the opener will be wiped and the new one will be in control. There are instructions that came with the opener that show how to do this from the remote or the key-less entry. If you are talking about an in-car device then your vehicle manual may be needed too, but the main thing is to set the GDO to be looking for the code from the car remote and when you press the in-car remote the garage door should respond. If you have programmed a remote or key-less entry then it is about the same procedure.
It is possible that the receiving unit on the vehicle is not operating properly. Whether that means a broken wire, bad circuitry in the receiver, or other problems it could the case, BUT more often than not, the key/remote was exposed to some kind of magnetic or high power field, effectively remdering the unit useless. Strong magnets, electromagnetic fields or even staying to long on a department store demagnetizer could lead to these problems. Go to the dealer and be prepared to take the hit, a replacement coded key can run several hundred dollars, but unless you swapped the battery and happened to get a bad new battery, than the dealer is the only solution, I hope this brief explaination shed a little light for you in the future.
