lock and unlock from driver side door with the key will reset the system
ok have you tried relearning the key
1. Insert an already programmed master key into the ignition. Do not turn.2. Press and release the gas pedal 5 times. 3. Press and release the brake pedal 6 times.4. Remove the key from the ignition. 5. Insert the new key you want to program into the ignition.6. Press and release the gas pedal one time.7. Wait 1 minute. The security light will be blinking for this one minute. When it stops blinking your
key is programmed. To end programming step on brake one time.
NOTE: Look for your security light. This light will guide you during the programming procedure. The security light will go off at Step 1. It will remain off until Step 6. The security light will come on and start to blink after Step 6 until the key is programmed. If the security light comes on after Step 4 STOP the procedure and start over again.
If you perform this procedure too slowly your car will not go into programming mode. If you can not get your car to go into programming mode make sure you are using a master key and not a valet key. If you have a master key then you will probably need to perform this procedure more quickly.
instead of putting the new key in just use the orignal key
no its not the car is morethen likely not registering the key
it will untill its been reset
let me know
ok do you have access to a scanner that dose live data
ok the theft system is going to have to be reset via a scanner when you removed the headlights the computer thought the car was being stolen so it is going to have to be reset that way just thought we would try the key first to make sure
did you disconnect the battery before you removed them
there are sensor is front of the car as well as the doors anytime you do anything like that it is best to disconnect the battery and it happens more often then you think
beside going in with a scanner and reseting there is really nothing you can do you have tried everything else as far as reseting the system
I see that you have not been able to get this resolved. Have you been able to get it restarted yet? Do you have the vehicle identification number available? Has there been an aftermarket security system added to this vehicle? Do you have a picture of the security light that flashes when the key is inserted into the ignition cylinder? At this point does the engine crank over or when you turn the key to start position there is no response from the starter?
Can you send me a picture of the security light flashing? I'm trying to determine what type of system this has on it. Do you have the vehicle identification number available?
I just verified that that security light is in fact the immobilizer security light. If that light flashes steady and consistent with the key in the ignition lock cylinder or if it flashes a code for example two flashes a pause than one flash and it will not start the car, in other words the engine cranks over but it just does not fire up then the key is not programmed to the system. There is an immobilizer chip in the key that once the key is inserted into the lock cylinder the transponder key coil around the lock cylinder recognizes the chip and sends a signal to the immobilizer system to tell the computer that it's okay to allow the engine to start. This vehicle will not start until that light stops flashing and the key is programmed. Do you have an original master programmed chip key that starts the car? If you do then I can walk you through a procedure to try and program this key that is not starting the car.
Do you have a code reader or can you borrow one from a local parts store to see if there any malfunction codes set in the engine control computer that may help understand why the transponder is not recognizing the keys anymore? This is a long shot but disconnect both battery cables isolate them from the battery and then place a jumper wire between the two cable ends let it set for about 10 minutes then remove the jumper wire reinstall the battery cable ends insert the nation key and see if the light stops flashing. Also using one key at a time inserted into the ignition lock cylinder monitor the security light does it flash slow and steady as if the key was not inserted or does it seem to flash a pattern for example a two flashes then one flash?
Ok let me know if there are any codes set in the computer.
