Spare Car Key Duplication FAQs
Straight answers from automotive locksmiths with real bench and diagnostic experience.
Why is getting a spare key cut so much cheaper than losing all keys?
With a working original, our optical and laser equipment can directly decode the mechanical bitting and clone or add the immobiliser cryptographic data without having to pick your vehicle’s locks, pull security PIN codes via dealer servers, or bench-flash the engine control unit (ECU). It turns a complex £600+ emergency into a simple £95–£165 scheduled appointment.
What vehicle documentation do I need to supply?
As professional automotive locksmiths adhering to UK security standards, we require proof of legal ownership before programming any electronic key or remote. You will need your V5C registration document (logbook) and a matching photo ID (driver's licence or passport).
