Hello. Welcome to Just Answer. Please allow me to assist you.
Personally, if the vehicle was in my shop, I would be "tracing", and removing the failed aftermarket alarm. The first step is to remove the lower panel under the steering column, and locate the wires that are interfaced with the wires on the ignition switch.
Is this something we can do or do we need to tow it somewhere else. The mechanic says he doesn't do anything with alarms?
Without knowing the type of system installed, or seeing the wiring, it is impossible to accuratly describe what one needs to do exactly.
I would do this:
Remove the lower part of the dash (the plactic above the driver knees
Locate theignition switch and its wiring connector
See if wires are soldered onto any of the wires.
If so, follow those wires until you see a black box of some type.
If mechanically inclined, remove all of the soldered-in wires, and tape up all the connections. In other words, remove the system entirely.
If you cannot operate a soldering gun, I would take it to someone who is qualified to work on electrical wiring
Do you think it is the alarm system that is keeping it from starting?
that is a 50% possibility.
The other 50% might just be a bad ignition switch. That can be checked with a 12 volt testlight
Is that the same thing as a starter?
the testlight? No
The ignition switch is connected to the back side of the cylinder that the key fits into
Is that not connected to the starter? I would have thought they would have checked that if they were looking at replacing the starter.
On the starter, there is a small wire. This wires is connected to the ignition switch. When the ignition switch is turend to Start, the small wire is energized, thusly allowing power to flow into the starter. If the ignition switch is bad, it will not energize this wire. If the alarm is stopping the electricty form getting to the starter form the switch, the starter will not spin. Some people forget this whilst changing starters. It is worth the effort to have the small wire checked for electricity. If there IS electricity, the starter may be bad, new or not
....But it sure does not sound like the alarm is the culprit here
DO you have any other questions for me today?
No I think that's it. Thanks. It sounds like the same thing we have already been told.
