Every key fob sold includes the following:

1. Key fob remote as described in the product listing
2. New battery installed

Simply search for your Make/Model/Year on our website (ex. - "2009 Ford F150"). It’s important to get the correct remote for your vehicle. You can do this two ways:

1. Check an existing remote - Just check the back or inside of an existing fob. ALWAYS get the same button configuration.
2. Check the VIN - If you do not have an existing fob, call a Dealership with your VIN to get the Part Number you need.

If you have any questions, feel free to contact us at [email protected].

Hold tight!  We are getting new stock in every day. Simply sign up for the Waitlist on the correct product's page and you'll be immediately notified when it comes back in stock.

We will help ensure that you get the correct remote for your vehicle or make any modifications to your order! Just reach out to our support email [email protected].

For many vehicles, yes! It's easy and anyone can do it! Check out our Free Programming Instructions for easy step-by-step instructions to program your remote.  If your vehicle requires professional programming we let you know on each vehicle specific programming instruction page, so you're not left with any doubt and searching all over the internet.  We recommend that you use our Auto Locksmith finder to have a Locksmith come to you and program the remote for cheaper than a Dealership: Auto Locksmith Finder.

We STRONGLY recommend that you call a local Automotive Locksmith for this service.  Locksmiths are generally more helpful, skilled at remote programming, won't refuse service and are more reasonably priced than Dealerships for remote programming.
You can find an Auto Locksmith near you with our Auto Locksmith Finder.

Yes! We ONLY sell "OEM" - original factory/manufacturer electronic key fob remotes.  Just like those from your local Dealer but for about 70% less, saving you from the Dealership markup.

Of course! We only sell OEM quality key fobs in a few different conditions:

1. Factory Sealed - These are genuine OEM, factory sealed key fobs.
2. New, Never Programmed OEM - These are Genuine OEM, new, never programmed fobs. They are bulk packaged and not in a factory sealed bag.
3. Lightly Used, OEM Refurbished - This is a lightly used, Grade A, refurbished OEM fob. They have been professionally cleared and are ready to program to your vehicle, with a new battery installed and uncut emergency key included (if applicable).
4. OEM Electronic - These consist of an OEM Circuit Board with an Aftermarket Shell (No Logos), with a new battery installed and uncut emergency key included (if applicable).

If you have any questions, feel free to contact us at [email protected].

OEM - These products are manufactured by the Original Equipment Manufacturer.  Meaning this is the same product that you can purchase at the Dealership.  These products are high quality and superior to "replacement" remotes being sold on the internet.
