2011 Scion XD Remote Head Key Replacement - Fast, Affordable & Professional
A customer's 2011 Scion xD was sitting at a Meineke shop near the Simi Valley Dog Park. The shop had called another locksmith to cut a replacement key after a brake job, and that locksmith got an immobilizer fault mid-program and walked away. Told the shop the computer was bad.
The shop called me. When I got there the ECU was rejecting every key registration attempt through the OBD port. Classic sign of a botched 4D-67 write on these Denso units. The immobilizer counter was stuck in a security lockout state that no amount of retrying from the diagnostic port was going to fix.
I pulled the ECU from behind the glove box, opened the case, and connected my ACDP bench tool directly to the 93C56 EEPROM. Read it, found the corrupted immobilizer data, cleared the fault bytes, wrote it back clean. Reinstalled the ECU, then registered a fresh MOZB41TG remote head key from scratch. Three-button, TOY43 blade, 4D-67 chip. The immobilizer accepted it on the first attempt after the reset.
I showed the Meineke guys what happened so they would know the warning signs if another locksmith ever left them in this spot. The whole thing ran about 75 minutes including ECU removal and reinstall. The alternative was a flatbed to the nearest Toyota dealer, a multi-day wait, and a bill that would have been a lot heavier than mine.
I carry bench tools for exactly this situation.

Reviews From Happy Scion Customers
Mobile service that comes to you
“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”
“I had two Subaru key fobs made and Marco provided excellent service. He stayed persistent through multiple part orders to make sure everything was correct. Very thorough, punctual, and great communication throughout.”
“Tim went above and beyond. I struggled all day trying to program a new FOB and nothing worked. Tim helped me patiently, even recommending cheaper options since I was on a tight budget. He eventually came all the way to Ojai late at night and fixed everything.”
