with a two-stage unlock feature that
unlocks only the driver door upon first
press of the unlock button and then
unlocks all doors when pressed again, cut
the unlock wire and continue to Step 6.

after the wire is cut but the passenger
doors do not unlock, follow the
directions for
Built-in Driver Unlock Relay
Only
. If the doors no longer unlock,
follow the direction for
Two-Step Type
or
Universal Two-Step Type
.

buit-into the keyless entry
module in this system type.

below the system will arm
or disarm only with the
keyless entry transmitter,
and the door switches will
have no affect on the secu-
rity system.
