VIN ? (USA car?)
what is the problem ("still does the same thing", does WHAT? (wrong or good or both)
did you add wireless remote starter on this car,
did it fail before or after the ADD.
THE real KEY SWITCH FAILS TO CRANK THE ENGINE.
IS THE STARTER MOTORS DEAD AND SILENT?
FIRE to Solenoids?, gets 12vdc power not fire, a voltmeter measures all this if you use one., there is no FIRE there ,it's voltage (power)
surely no 98 car came with factory remote start, (SM says NO)
so there is a story to tell but not told
nor full symptoms told , using a normal key or this wireless secret device./< none told.
worse yet cars with IMMO, the manual tell us flat out, not compatible with remote starts (none-OEM)\
there are no 2 aftermarket (non-OEM) remote start kits the same.
for sure safeties..
IMMO rules VW
VW is 1999 or earlier and sold in North America, it shouldn't have an immobilizer.
but
If your car has the yellow car/key symbol on the instrument cluster (shown activated below) it has an immobilizer.
as you can see a 1998 car is just blow,1999 start year
some cars made after July 1st,1998 have 1999 opitions.
so nobody guess what is there in your car , factory options
Most IMMO cars do not allow lacks the car starting and running systems.
(it THINKS you are hacking it) see?
read here carefully about IMMO.

note: from there, (immo on this car is very odd)
Cabrio and Eurovans have no immobilizer warning light and the
immobilizer module is separate from the instrument cluster.
that means no cute carbody+key lamp is there in the cluster.
for easy immo discovery.
outside USA IMMO happened sooner and not told you ,your country.
a good aftermarket IMMO maker If this is the topic, NOT TOLD
may have LED status lamps to tell what input is failing
this is key(no pun) to the solution, failed.
and a manual for the IMMO telling how to troubleshoot.
a voltmeter is always used, if savvy tech, a $15 tool.
the IMMO can block
cranking
and spark then fuel.
immobilized.
so can remote starts, OEM remote starts block cranking for a huge list of things, even doors not closed/locked, tranny in gear, or PCM errors.
or TCM errors. and more, remote starts are dangerous.
