Question about some Toyota/Lexus driver lock codes.

[darknezz19]

Sometimes I get a code stamped that doesn't fallow instacodes range. For example I think the last 2006 Corolla I did had a stamp starting with C and had at least one other letter. Can we decode these into the format Instacode recognizes?

had a few weird ones myself on some 05 06 solaras with weird codes on the locks

only thing i could think of was that they had been replaced with an aftermarket set

in which case you need to make a key for the door and figure out whats left in the ignition
