This is an excellent "cheap" replacement part. The installation video was easy to follow and changing it was a breeze. The only downside to me is I have to carry the old key for doors and truck operation. I do use keyless entry but if the battery is dead you still have to manually open the door to open the hood for a jump. I've had 0 issues with this part and the security light is off. Most importantly, it starts every time I need it to. I will definitely buy from 1A auto again.

Better than waiting for the recall schedule
This worked just great tired of waiting for the recall schedule to fit into ours. Only thing to remember is you will now have 2 keys. I marked this I with paint stick and put 2 grooves in plastic so you wouldn't mistake the keys. Great product.

Is this a brand new part?
Keithyon M on Apr 18, 2018
BEST ANSWER: Hello! This part is brand new, yes. It also comes with our lifetime warranty.
MISTER on Oct 2, 2017
