BUICK LESABRE 1993 Repair Manual

When a new LeSabre, is delivered, the dealer removes
the plugs from the keys, and gives them to the fist
owner. However, the ignition key may not have a plug.
Each plug has
a code on it that tells your dealer or a
qualified locksmith how to make extra keys. Keep the
plugs in a safe place.
If you lose your keys, you’ll be
able to have new ones made easily using these plugs.
If
your ignition keys don’t have plugs, go to your Buick
dealer
for the correct key code if you need a new
ignition key.
Key Reminder Warning
If you leave your keys in the ignition you will hear a
warning tone when
you open the driver’s door.
Door Locks
A CAUTION:
Unlocked doors can be dangerous.
Passengers
-- especially children -- can easily
open the
doors and fall out. When a door is
locked, the inside handle won’t open it.
Outsiders can easily enter through an unlocked
door when you
slow down or stop your vehicle.
This may not be
so obvious: You increase the
chance
of being thrown out of the vehicle in a
crash if the
doors aren’t locked. Wear safety
belts properly,
lock your doors, and you will be
far better
off whenever you drive your vehicle.

service.
Operation
The
driver’s door will unlock when UNLOCK is
pressed.
If pressed again quickly, all doors will unlock.
All doors will lock when LOCK is pressed. The trunk will unlock when the opened trunk symbol
is pressed,
but only when the ignition is
off.
Matching Transmitter(s) To Your Vehicle
Each key chain transmitter is coded to prevent another
transmitter from unlocking your vehicle. If
a transmitter
is lost or stolen, a replacement can be purchased through
your dealer. Remember
to bring the remaining
transmitter with
you when you go to your dealer. When
the dealer matches the replacement transmitter to your
vehicle,
the remaining transmitter must also be matched.
Once the new transmitter
is coded, the lost transmitter
will not unlock your vehicle.
You can match a transmitter
to as many different
vehicles as you own, provided they are equipped with
exactly
the same model system. (General Motors offers
several different models of these systems on their
vehicles.) Each vehicle can have only two transmitters
matched to
it.
To match a transmitter, use the following instructions,
1. Have both transmitters that will be matched to the
car present, even if only one is new. Remove the car
keys from
the ignition and have them with you.
2. Find the 12 pin diagnostic connector above the
accelerator pedal.

5. Still keeping the program terminal grounded, repeat
Step
4 with the second transmitter. If you disconnect
the ground wire before completing this step, only the
first transmitter is matched.
If you make a mistake,
disconnect the jumper wire and start over at Step
3.
6. Remove the jumper wire. (Note: The system will not
operate
if the jumper wire is still connected.)
7. Test the operation of both transmitters with the
vehicle.
3. Use a jumper wire with alligator clips at both ends to
ground (Terminal
A) to program (Terminal G).
Grounding the program terminal erases the system
memory and causes the doors
to lock and unlock
once. This means
the system is ready to be matched
to the transmitter.
4. Keeping the program terminal grounded, press the
UNLOCK button on the first transmitter. The door
locks will lock and unlock again to indicate
the
transmitter is now matched. If there is no response,
check the transmitter batteries. If
you do not want to
match a second transmitter, proceed to Step 6.
If the lock control does not work as it should, see your
Buick dealer.
Battery Replacement
Under normal use, the batteries in your key chain
transmitter should last about two years.
You can tell the batteries are weak if the transmitter
won’t work at
the normal range in any location. If you
have to get close to your vehicle before the transmitter
works, it’s probably time to change the batteries.

For battery replacement,
use
two Duracell @
batteries, type DL-20 16, or
a similar type.
1. Remove the screw from the back cover.
2. Lift off the front cover, bottom half first.
3. Remove and replace the batteries. Put them in as the
direction under the batteries indicate.
To replace the batteries:

that help prevent passengers from opening the rear doors
of your car from the inside.

3. Do the same thing to the other rear door lock. The
rear doors of your vehicle cannot be opened from
inside when this feature is
in use. If you want to open a
rear door when the security lock is on:
1. Unlock the door from the inside.
2. Then open the door from the outside.
If
you don’t cancel the security lock feature, adults or
older children who ride
in the rear won’t be able to open
the rear door from the inside. You should let adults and
older children know how these security locks work, and
how to cancel the locks.

Although your Buick has
a number of theft deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways
you can
help.
Kev in the ignition: If you walk away from your
vehicle with the keys inside, it’s an
easy target for joy
riders or professional thieves
-- so don’t do it.
When
you park your Buick and open the driver’s door,
you’ll hear a tone reminding
you to remove your key
from the ignition and take it with
you. Always do this.
Your steering wheel will be locked, and
so will your
ignition and transaxle. And remember
to lock the doors.
Parking at Night: Park in a lighted spot, close all
windows and lock your vehicle. Remember to keep your
valuables out
of sight. Put them in a storage area, or take
them with you.
Parking Lots:
If you park in a lot where someone will
be watching your vehicle, it’s best
to lock it up and take
your keys. But what if you have to leave your ignition
key? What if you have
to leave something valuable in
your vehicle?

PASS-Key I1 TM
Your vehicle is equipped with the PASS-Key I1 TM
(Personalized Automotive Security System) theft
deterrent system. PASS-Key I1
TM is a passive theft deterrent system.
This means you don’t have to do
anything different
to arm or disarm the system. It works
when you insert or remove the key from the ignition.
PASS-Key uses a resistor pellet in the ignition key
that matches
a decoder in your vehicle.
When the PASS-Key I1
TM system senses that someone is
using the wrong key, it
shuts down the vehicle’s starter
and fuel systems. For about three minutes, the starter
won’t work and
fuel won’t go to the engine. If someone
tries to start your vehicle again or uses another key
during this time, the vehicle will not start. This
discourages someone from randomly trying different
keys with different resistor pellets in an attempt to make
a match.
The ignition key must be clean and dry before it’s
inserted in the ignition or the engine may not start.
If the
engine does not start and the “SECURITY” light comes
on, the key may be dirty or wet. Turn the ignition off.
Clean and dry the key. Wait about three minutes and try
again. The security light will remain on during this time.
If the starter still won’t work, and the key appears to be
clean and dry, wait about three minutes and try the other
ignition key. At this time, you may also want to check
the
fuse (see “Fuses and Circuit Breakers” in the Index).
If the starter won’t work with the other key, your vehicle
67

needs service. If your vehicle does start, the first ignition
key may be faulty. See
your Buick dealer or a locksmith
who can service the PASS-Key
I1 .
If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won’t work and the
security light will flash. But
you don’t have to wait three
minutes before trying one
of the other ignition keys.
See your Buick dealer or a locksmith who can service
the Pass-Key
I1 TM to have a new key made.
If you’re ever driving and
the “SECURITY” light comes
on and stays on,
you will be able to restart your engine if
you
turn it off. Your PASS-Key I1 system, however, is
not working properly and must be serviced by your
Buick dealer. Your vehicle is not protected by the
PASS-Key I1 system.
If you lose or damage a PASS-Key I1 TM ignition key, see
your Buick dealer or
a locksmith who can service
PASS-Key I1
TM to have a new key made.
