Stolen Car Keys: Will a Replacement Disable the Old Key?

A replacement key does not automatically disable a stolen key. Adding a working key, removing a missing key's electronic authorization and changing mechanical lock access are separate tasks. Tell the provider that the key was stolen so the work addresses that situation.

Auto Key SD offers both electronic key removal and mechanical rekeying. The options depend on your exact vehicle and lock system.

Electronic key removal addresses the missing key's authorization within the supported vehicle system. Ask which functions the procedure covers, including engine starting and remote access. A provider should explain the vehicle-specific procedure rather than promise that every system works the same way.

Mechanical rekeying changes a supported lock's key match. It addresses access with a cut blade. Removing electronic authorization does not change the physical lock, so a stolen blade may still fit an unchanged lock.

Depending on the vehicle and circumstances, one or both services may be appropriate. The work should be agreed before it starts.

Provide the year, make and model, your location and how many keys remain. Explain whether the stolen item was a remote fob, a key with a blade, or both. Tell us about visible lock damage or other vehicle problems that could affect the work.

Ask which documents establish ownership or authorized use, and whether all remaining keys must be present. Keep those keys available for the appointment.

Some situations require replacement lock components or another repair provider. Make sure the quote explains the agreed scope rather than treating “new key” as a complete description of the job.

• Are you adding a replacement, removing the missing electronic key, or doing both?
• Which electronic functions does the procedure address on my vehicle?
• Could the stolen blade still open an unchanged lock?
• Which mechanical locks would be rekeyed or replaced?
• Will my remaining keys still work after the service?
• What parts, programming, lock work, labor and travel does the quote include?

Do not assume it will still work after electronic key removal. Tell the provider if it is recovered and ask how it should be handled. Its electronic functions and mechanical blade can have different outcomes, depending on the work completed.

Test the retained and replacement keys with the technician. Check starting, remote functions and the mechanical locks included in the job. Ask for a receipt describing the completed work.

Ask the technician which access methods were changed and whether any locks or key functions need further attention. Since the stolen key is unavailable for testing, discuss how the completed procedure is verified.

Call (619) 535-8000 and explain that your key was stolen. We can discuss supported electronic key removal, mechanical rekeying and replacement options for your vehicle.
