The transponder code still works, so I can still use the key to start the car (and open the door), as long as the alarm never gets set

The keys didn't work it shut down my 2012 Chevy cruze LTZ when I brought it to the dealer for programming

I would highly recommend these replacement keys to everyone.

I love my keys

Dropped keys on the ground once and it shattered.

So i purchased my key fobs from amazon and had batteries plus program my keys for $35 they came to my house for a fee of $15 i saved so much money getting these keys and they work fine

cheap and once cut programmed easily by myself ( simply put old key in ignition and start car...turn off and remove and immediately put in new car and start) whala!

Also in hopes this may help someone in need, I completely lost my only and original key so this was a replacement not spare

they used my one good key to duplicate and they automatictly programmed themselves when I started the car
