Hi!
I know it might not be the best category to post this question, I didn't know where honestly.
I recently acquired a Mercedes Benz C200 2001-2003 and the remote key has a problem which I'm not able to figure out. The key remotely lock the car, can start the engine of the car with no issues but I can't unlock the car from the key. I have to use the physical key and immediately insert the remote into the ignition so the alarm doesn't go off too long.
We've opened the key up and looked for corrosion and loose connections but nothing of those appear. We've measured and tested every part of the key to see if power goes through it or if the contacts are good and everything is fine. When pressing the lock button the key has a small led that lights up showing that the command was sent, but when the unlock button is pressed, the led doesn't light up.
Any suggestions or advice?
Sorry for the long post!
