Questions before you buy
How do I know this fits my car?
Match the FCC ID on the back of your old remote, or the model of your alarm system (on the alarm’s control unit or in its manual), to the one in the specifications on this page. These fit the alarm, not the car, so a VIN can’t tell. Not sure? Send us a photo of your old remote.
Which condition should I choose?
All conditions do the same job in your car: same buttons, programmed the same way. The difference is how it looks and what it costs.
- Pre-owned: genuine and tested, in its original case with visible wear. Works the same, costs less.
Do I need to program it, and how much does that cost?
Yes, to your alarm system. Most alarm remotes learn with the alarm’s valet or program button in a few minutes, no tools, no cost; the steps come in the box. If your system needs it, an installer can program it.
Will my old keys still work?
Program all your remotes in the same session. Most alarm systems forget any remote that isn’t programmed along with the new one.
What if it doesn’t work with my car?
Call us first. Most problems are solved on the phone. If the part doesn’t fit or won’t program to your car, you can return it within 30 days. See our return policy.
How fast will I get it?
In-stock orders ship from New Jersey with tracking. Shipping options and prices are shown at checkout before you pay.
