FAQ

Frequently asked questions

Can I program a car key without any tools?
Sometimes. Many domestic models let you add a transponder or remote key on-board if you already have one or two working keys, no tools required. Smart / proximity keys depend on the make and year — some add on-board, others need a programming tool. All-keys-lost usually needs a pro.
Do I need the dealer to program my key?
Usually not. A good auto locksmith can program almost anything a dealer can, often cheaper and at your location. For European makes like Audi and VW, a specialist locksmith is actually the right call.
How long does key programming take?
On-board DIY programming takes a few minutes once you have the sequence. A locksmith visit is usually 15 to 30 minutes, including cutting the blade if needed.
Will my new key start the car right out of the package?
No — a chipped or smart key has to be programmed to your specific car first, and the blade may need cutting. Plan on one of the two routes above before it’ll start the engine.
What do I need for a locksmith to program my key?
Proof the car is yours: your registration or title plus a photo ID. A trustworthy locksmith will always ask, which protects you and your vehicle.
