GENERAL INFORMATION
KEYS AND LOCKS
Every key has a number engraved on one side which
identities the key blank manufacturer. On the oppo-
site side of GT keys, is a removable adhesive foil on
which, the profile and cutting code letters and num-
bers are imprinted. Attached to the protective key
cover of Opel
1900
and Manta keys, is a tab on which
the profile and cutting code letters and numbers are
imprinted. Record the key cutting code letters and
numbers before the adhesive foil or plastic tabs are
discarded as this information is necessary to obtain
replacement keys.
In the event of lost keys and code records, one or
more locks may be removed to obtain the code num-
bers. The codes are stamped on the trunk and igni-
tion lock cylinders and on the door lock plunger
shaft. If a lock cylinder is damaged, it must be re-
placed. This then means that the owner will have an
additional key.
