Reading Key Blanks

Service body and compartment locks are supplied to the body builder by lock makers, and a single vehicle usually runs one key across every locker so that a technician is not carrying a bunch. That also means a lost key opens the whole vehicle.

The code is stamped on the lock face or on the original key. Take it from there rather than from the body or the chassis, and rekey the set rather than one door if a key goes missing.
