Lost all keys?
Call with the VIN and vehicle details to check whether we can support your all-keys-lost situation. We will confirm what is needed and any proof of vehicle ownership or authorization required before service.
Key supplied by you?
Not every aftermarket or previously used key can be programmed to every vehicle. Contact us before buying a fob so we can discuss the correct type and service availability.
Mobile or Oceanside shop appointments

BOOK A SERVICE →Key fob not detected or the vehicle will not start?
A key-recognition warning does not automatically mean the key needs replacement. The key, vehicle battery, immobilizer system, wiring or a related module may need diagnosis. Tell us the exact message on the dashboard and whether a second key works.
Spare key or all keys lost?
Adding a key while a working key is available can be a different job from an all-keys-lost situation. Availability and requirements depend on the vehicle and security system. Call before arranging transport or buying a replacement key so we can confirm whether the requested service is supported.
What should I bring to the appointment?
Tell us how many keys you currently have and whether each one starts the vehicle. Ask which keys to bring and what proof of ownership or authorization is required for your specific service. If you already bought a key or fob, have its part number available for a compatibility check.
If the key issue followed a module replacement, review our OEM programming and coding services.
