Universal Basic
The universal basic connection type offers very easy connection to any keyless enty
system, but is also the least secure method due to the lack of door lock switch iso-
lation.When connected as
shown below, the system
will arm or disarm with
the keyless entry transmit-
ters and with the door
lock switches. If the vehi-
cle is equipped with two-
step unlocking, it is strong-
ly advised to follow the
directions for
Universal
Two-Step
instead.

Built-in Driver Unlock Relay Only
This system type, often found on GM vehicles (especially GM trucks), unlocks only the driver
door on the first transmitter button press, and unlocks all doors on a second button press.
The door lock switches out-
put a positive trigger, and the
door lock relays are usually
seperate from the keyless
entry module. In this system
the keyless entry module fea-
tures a built-in relay to
unlock only the driver door.
