1. Insert key in ignition and leave in the OFF position
2. Locate the Data Link Port. It is located under dash drivers side. Be sure you know which pins are 8 and 4. (Note port is wider at top) Your OBDII port will not
have numbers.
3. Make sure there are metal contact pins in terminals 8 and 4. Connect 8 to 4 with a
suitable jumper wire (leave the jumper wire connected throughout the programming
procedure). Make sure you know which terminals are 8 and 4. The vehicle will respond
by locking and unlocking the doors to signify entering of programming mode.
4. Close doors.
5. Turn ignition to the ON position (as far as you can go without cranking the engine).
Doors will lock.
6. Press and hold both the LOCK and UNLOCK buttons together on the first transmitter to
beprogrammed. After about 15 seconds, the vehicle will respond by locking and
unlocking the doors. Release the buttons on the transmitter.7. Within one minute, repeat the previous step on the remaining transmitters to be
programmed.
8. Remove jumper wire applied to the OBDII Port.

SOURCE: 1995 Buick LeSabre - horn blows
My horn would honk without any assistance from me. The
reason was because the plastic cover for the air bag and horn switches had
shrunk so tight that it pressed on the horn switches. If your problem is
intermittent then cold temperature would also cause the cover to shrink. This
is how I solved the problem on my 1995 Buick LeSabre:
Disconnect the negative battery cable.
2. 2.
There are two plastic twist locks (turn ¼ left) and one small wing nut holding
the cover on. When the cover is off I see two black fuse covers side by side
and below them are several relays. Some are gray and some are black.
3. My
horn relay was the second from the left as I faced the rear of my car. It was
gray. Some may be black.
4. A
small green retainer tab had to be pushed out before I could pull the relay
out. On the back of the relay were two orange wires that supply 12V. One green
wire that goes to the horns and one black wire for ground that goes to the horn
switch under the air bag.
5. I
cut the black wire and wired in a spst push button switch that I connected to
ground.
6. I
mounted the push button switch near the driver’s door on a flat part of the
dash. I used very strong double sided tape to secure the button switch to the
dash.
My horns now are activated when I
push my new horn switch button. My problem solved.
Someone recommended removing the
air bag/horn switch unit from the steering wheel and relieving the tightness of
the plastic cover. There are probably more than one way to this.

The problem is the crankshaft sensor for sure. It is mounted behind the crankshaft pulley which is pretty difficult to get off as you need a special puller. A shop should charge about 1.5 hours for this job. It is a very common problem.

Aparrently you have to reset the remote, I have the same problem and a trying to figure out how to reset it.
