EEPROM, BCM & Immobilizer Module Programming in Michigan
When a job requires deeper module work — EEPROM reads, BCM programming, or immobilizer resets — we have the equipment and experience most locksmiths don't.
Quick Answer

FAQs
What is EEPROM in a car key context?
It's the small memory chip inside an immobilizer module that stores key data. Reading it lets us recover or rewrite key information.
Is module programming risky?
Done correctly with the right tools, no. We back up data before any write.
