Identify before you program.
Most "DIY key fob" sites copy-paste the same ignition-cycle steps from a 2007 owner's manual. We start one level earlier: what fob does your vehicle actually use, what chip is inside it, and which aftermarket tool can pair it? Get those three answers right and the programming step is the easy part.
Find your transponder chip
The single most useful piece of information when shopping for an aftermarket fob — and the one most listings get wrong.
Already own a programmer?
Click yours to see exactly which makes, model years, and chip families it can pair — and where it falls short.
Built for owners, locksmiths, and DIYers.
We don't sell fobs. We don't take affiliate kickbacks for sending you to a particular locksmith or a particular tool. The directory is supported by display advertising, which means our incentives are aligned with yours: write a guide so accurate you actually get your fob paired the first time.
