En cuanto se programa la llave el chip trabaja sin problema ‘

For those who are struggling to make your newly cut key work, bear in mind that the new key must be programmed by a dealer or a locksmith who has the software to code your key. If your newly cut key can turn on the lights, the cutting part was done correctly. However, without programming, it won't start the engine. You may follow some online instructions to "program" your key, but only to a point where your remote buttons work, and the key won't start your engine. This is because your new key must be programmed and authenticated, and the authentication identifier must be saved in your car. The battery in your remote only powers the remote functions, but the identifier on your new key is coded on the piece of firmware in your remote which does not lose the identifier information even when the power source is off.

Easy to operate but you need to use blades to open it just like the official one. Anyway cheaper than the official one and kinda great deal
