2003 GMC Envoy Remote Replacement - Fast, Affordable & Professional
Lock decoding means I read your car's lock to create a key without drilling anything, without breaking anything, and without replacing the lock cylinder. The car looks exactly the same when I leave.
A hiking guide at the trailhead lot outside National City realized his key was gone. It must have fallen out of his pocket on the trail. His 2003 GMC Envoy was sitting in the dirt lot with no key and he was two hours from the nearest GMC dealer. He called another locksmith first, and that locksmith told him the ignition might need to be drilled and replaced. That quote was over $500. He called me for a second opinion.
I used my B111 Lishi to decode his door lock and read each wafer position inside the cylinder without touching or damaging the internal components. That gave me the exact cut depths for a new key. Once I had the code, I cut a fresh blade, built the transponder, and programmed it through OBD. His remote, FCC ID MYT3X6898B, was a 3-button unit that I paired to the truck's body control module as part of the all-keys-lost procedure.
No drilling, no cylinder replacement, no new ignition assembly. Total was $91. The other locksmith's plan would have been $195 or more with a new cylinder and keys. His original lock works with the new key exactly like it worked with the one he lost on the trail.

“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”
“I called over 40 locksmiths trying to get a key made for my Audi A6 and nobody could do it. Tim made it easy, fast, and affordable. He showed up with a smile and got the job done without any stress. Absolute wizard with keys.”
“My Chevy key snapped while I was running errands in North Oxnard. He removed the broken piece from the ignition, cut a new blade, programmed the transponder, and tested everything thoroughly. The whole job was smooth and professional. Best automotive locksmith I have used.”
