Eventually Tracker key fob buttons wear out. A pair of new fobs can be had for less than $40.



New fobs are not programmed with a scanner. You could do it with a bent paper clip but that is easier said than done.


The DLC jack is located in the least accessible part of the footwell. There's little room to get your
head in there and even less room to move your arms around. The DLC connector is mounted upside down
and backwards. The chassis ground on pin 4 has to be shorted to pin 8 which is directly adjacent
to pin 16 (battery voltage hot at all times). A paper clip is just asking for trouble. It's safer to build
a dummy plug.


An empty DLC shell can be had for a few bucks on the internet.


Solder a jumper from pin 4 to pin 8.


You can install the dummy plug by feel and it won't fall out during the programming procedure.
Up to four fobs can programmed for the Tracker.

 

I've got a question about this procedure. In the FSM the procedure is different, as pictured below. Since Chevy Trackers are rebadged Suzuki Vitaras/Grand Vitaras, the process would be the same, right? Unless both methods work?

 

Although both the Tracker and Grand Vitara were built in same CAMI plant in Ontario, Canada; the two cars are not identical.
In the case of the key fobs, Chevy went with the programming method used by most other Chevrolet vehicles at that time.
Keep in mind I have a 2001 Tracker so that is the only year I can speak to with authority. I checked my 2001 Suzuki FSM
and surprisingly it does not show a key fob programming procedure. A little more searching found this on a Suzuki forum:
"There is NO way to reprogram the 01 units. You must replace the control unit and new key fobs. The 03's are the first ones
that you are able to reprogram."

 

I did a little more digging on the Tracker vs Grand Vitara keyless entry systems.
Apparently there is a Suzuki Technical Service Bulletin (TSB) addressing this issue.



I looked up this unit. It fits the Grand Vitara but not the Tracker.


Here's a guy (Razteo) who tried to replace the keyless entry system in his Grand Vitara.

 

I managed to get a photo of my Remote Control Door Lock Receiver module.


It looks like this module was used in a number of GM vehicles.


Supposedly you can still buy these modules on ebay for $95.


It even comes with two key fobs.


This is clear evidence that the 2001 Tracker and 2001 Suzuki use different door lock modules. It also explains why I could never reconcile
the Tracker schematics with the Suzuki prints. The Suzuki module drives the door lock motors directly. It also energizes two "answer back"
relays that flash the turn signals and tail lights. The Tracker does not have "answer back" relays but it's door module energizes two relays
that in turn drive the door lock motors.
