Car key services

Car key, smart fob, and EEPROM programming in Murrieta.

We program supported transponder keys, remote-head keys, smart keys, and proximity fobs. When ordinary OBD programming is not available, an EEPROM-based key or immobilizer solution may be evaluated.

Car key services from US Locksmith & Supply

Standard diagnostic programming

For supported vehicles, we connect professional key-programming equipment, access the immobilizer procedure, add the compatible key, and test starting and remote functions.

  • Transponder keys
  • Remote-head keys
  • Proximity and push-to-start fobs

EEPROM-based key solutions

When a supported key job cannot be completed through ordinary diagnostic programming, we may read immobilizer-related data from the appropriate module to prepare or add a key. The exact procedure is vehicle-specific.

  • All-keys-lost recovery on supported systems
  • Immobilizer data reading
  • Bench-based key preparation when required

What we do not advertise

EEPROM key work is not the same as general engine-computer service. We do not offer ECU tuning, performance flashing, emissions programming, or general ECU repair.

Customer-supplied keys

We can evaluate some customer-supplied keys, but appearance alone does not prove compatibility. FCC ID, frequency, part number, chip, board condition, and lock status can all matter.

Questions before service

Answers for this automotive service.

What is EEPROM key programming?

It is an advanced vehicle-specific method used on some immobilizer systems when standard diagnostic programming is unavailable or insufficient. We evaluate support before accepting the job.

Do you program or repair ECUs?

No. Our advanced work is limited to supported key and immobilizer-related EEPROM procedures. We do not provide general ECU programming, tuning, or repair.

Can you program a key I bought online?

Sometimes, but only after the FCC ID, frequency, part number, chip, keyway, and condition are checked. Programming success cannot be guaranteed for an incorrect, locked, damaged, or previously used key.

Should I bring every working key?

Yes. Some procedures can change which keys remain authorized, so bring every key you want to continue using.
