Key Fob Programming
Smart keys, proximity fobs and remotes programmed to your vehicle, or a spare added before you lose the only one.
Short answer: Key fobs, smart keys and remotes are programmed to your vehicle with dealer-level tools from the van, whether you bought a replacement fob, lost one, or want a spare added before the only one fails.
What programming actually does
Every fob has a unique code that the vehicle's body module and immobiliser must be taught to accept. Programming pairs the new fob to the car and, on an all-keys-lost job, erases the lost fobs so they can no longer start or unlock it. Some vehicles allow on-board programming with two working keys; most modern ones require diagnostic equipment.
Bringing your own fob
Aftermarket and online fobs can be programmed when they are the correct part for the vehicle's frequency and chip. Low-quality units sometimes fail to pair and you are told before programming time is spent. If in doubt, ask before buying and the right part number can be confirmed.
Dead fob vs. dead battery
Shrinking range and needing to press twice usually mean the coin cell is fading, not the fob. That is a two-minute fix. See the fob battery and longevity guide before paying for programming you may not need.
What it typically costs
Programming a fob you already have typically runs $75 to $200. Supplying and programming a new smart key ranges widely by make, roughly $200 to $500. Ask for the total with the part included.
Every job is quoted as a total, on the phone or before work starts on site. Ask for it, and see the full pricing guide for what drives the number.

Can you program a fob I bought online?
Yes, when it is the correct part for your vehicle. Cheap clones sometimes will not pair; you are told before time is spent, and the correct part number can be confirmed in advance.
Do you need all my existing keys?
Bring every key you have. On an all-keys-lost job the missing ones are erased for security; on a spare-key job the existing keys keep working.
Does a dead fob battery need programming?
No. Replacing the coin cell restores range. Programming is only needed when the fob is new, lost or has genuinely failed.
