Very nice product.
This is a very accurate copy.* Everything fits well, except one important thing. The knob of product isn't the same as the original, and also its sockets in the key box, with results, when replacing the dummy key with the original car key, not to lock in side the key slot but staying extended outside. (see photo). I found solutions. you have to trim with cutter the two edges shown in photo and then it fully closes. Very useful product but 4stars because of the time it took me to find solution and fix it.
The remote key i repaced was from an OPEL ASTRA J 2010.
