Review: Works well - Good key, seems well made. Ive just coded it and it works fine. The only thing is it doesn't have Merc logo on it
Review: Decent quality pcb for a key - I've used a lot of these keys because I can get them the next day. They have all so far been good quality and no issues programming them in.

### ⭐ Disappointing purchase

I needed to replace the back of my key fob as it had been removed when parked at Meet and Greet. Although it was supposed to be an exact match the replacement back didn't fit so a waste of money
