2003 c230 Remote Key Fob Malfunction: No Lock or Unlock

I really need your feedback!

I have 2003 c230 coupe. The two keys do not work to lock or unlock the car though they can start the engine. I took the car to the dealer and after testing several things (including replacing the old batteries), they said I needed a new key, so I ordered one. It can start the engine but it still can't lock or unlock the car. In this case, should I reprogram or reset the new key? Or, what DIY ways are available before taking this to the dealer? It is very frustrating so I really appreciate your constructive feedback!

Did you recently get your car tinted? It could be the RF reciever in the car that's malfunctioning.

Yes, I had windows tinted. Is it because of that? In this case, what should I do? I appreciate your reply!

Again! - this comes up too often. These tinting guys really should know better with modern vehicles.

Post C230 W203 Key Remote stopped working

I swapped out the batteries, ignition starts, but cannot open lock doors using the key remote. Any ideas? Had tint for 10 years, so not tint.

What fuses should I check? There are a lot!

Thanks!

Thumbs down RE: Key fob not working for C230 K

Well it looks like it is the key fob that is the issue. With new batteries it didn't work any better. I switched to my spare key which is kind of beat up (plastic messed up) and the key fob works much better by opening and locking the doors remotely.

It still has the occasional glitch when I place in the ignition and the engine does not fire, so I have to turn the key to the left, start over and turn to the right again.

I guess I need a replacement key for the faulty one - since you can't reprogram the key yourself. The manual indicates if it stops working, just insert in the igintion and turn and the key resyncs...

If you do end up having to buy a new key, try several local dealerships; prices are all over the place.
