Replacement Keyless Entry Remote Fob Key Shell Case for Mercedes Benz W203 W210 W211 AMG W204 C E S CLS CLK CLA SLK Classe IYZ3312 No Chip

Pero ya me dio hueva regresar la dije por que me sirva por un tiempo el platico nada resistente se barrio y subió y tuve que romperla para sacar la llave

Very quick and easy fix for a worn out original key. Electronics easily transferred over, fit was exact. Looks like new again!Please ignore one and two star reviews by morons who did not read the description and bought this expecting it to unlock and start their car. Really?

se ve linda la carcaza pero no sirve tuve que pagar un cerrajero que la cambiara y termino vendiendome otra por 300.00 dlsNo es solo cambiar la tablilla y baterias a la nueva carcaza, la original tiene un chipp imposible de cambiar y no es util a ese punto. No pude encontrar un cerrajero que me la p udiera cambiar... Asegurate de poder cambiuar el chip integrado a la carcaza si no no lo compres

I installed the original key electronic board in the new one, but the key buttons would not work to lock and unlock the vehicle it also does not have a red indicator light to show the new key is working or not.

None of the buttons work. I transferred the circuit board and key from my old fob and installed new batteries. Lock button doesn’t click at all. The other buttons do click but nothing happens. It does start the car.
