Question about 1998 Mercedes-Benz C-Class

4 Answers

My MB 1998 C280 remote key does not work all the time when I insert it in the ignition. I had batteries replaced but am still experiencing key not going in ignition. Up until today I could press the lock and unlock pad on the remote and it worked. Today nothing worked. Is this an ignition or electrical problem?

It could also be a low/weak voltage on the main battery. I was experiencing similar problems (seats too) and now they are gone.

98 intrigue keyless entry


Here's what i found.

1. Close all doors.

2. Insert key into the ignition cylinder but do not turn it.

3. Press and hold the Unlock button on door lock switch on drivers door.
Hold until instructed to release in step 6.

4. Remove key from ignition and then insert key into ignition without turning ignition cylinder and remove key.

5. Insert key in ignition a third time and leave key in ignition. Do Not turn ignition.

6. Release door lock switch on drivers door panel.
A Chime will sound 3 times indicating that you are in programming mode.

7. Press both the Lock and Unlock buttons on the remote up to 30 seconds.
A chime will sound 2 times if remote has programmed successful.

8. Repeat step 7 if you are programming additional remotes.

9. Remove key from ignition to exit programming mode.

NOTE: If you are having trouble getting this procedure to work, we have found that some vehicles need step 3 to be done before step 2.

Did you make sure to pull the key out after the procedure? This closes the "programming mode".

Well the remote was dropped and came open,the battery flew out.i replaced it but the truck lockes won't respond.


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.

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.

Central locking not working on key.


Before you spend bigger amount, check the battery in the key. Usually a CR2032 battery can be find there. (Open the Keyfob by inserting an object into the key ring holder and pulling the top and bottom apart, Seperate the two halfs, Open the top half to expose the battery... )

1994 C280 wont start


You left the key too long in the ignition switch. This sent an alert as if it were being stolen. Remove the key from ignition. Lock all doors. Wait about an hour or so. When you open the doors, put your foot down on the gas pedal and release. Put the key into the ignition and turn the car on.  Make sure you have the shift in "Park" position.
