There is a question that in some states it may be ******* and you could be liable in a law suit.

Probably just as easy to repair the fault than to disconnect or remove the alarm, which could be just plugged into the fuse box or more likely buried in the dashboard to discourage people from disconnecting it.

The alarm is generally switched off by a switch built into the seatbelt stalk. The presence of wires will verify this. The wires might have been damaged or become unplugged or the switch stopped working. Lots of dust and stuff finds its way down there.

I suggest you take care not to confuse any wiring for seatbelt pretensioners.

Have the same problem in my 98 Toyota Rav4. I squirted the female buckle (bolted to seat, not holding strap harness) with wannabe WD-40 lubricant from the $1 store, and it seem to have solved the problem. I'm guessing the spring mechanism is worn out, which is why the harness buckle won't lock. Another solution is to replace the female lock buckle with an identical part from the used parts junkyard store.

The seatbelt light on the dash stays "on," even when everyone has their belt on, but I don't bother servicing that. If yours have an audible alarm instead of an indicator light on the dash, locate the source of the alarm sound and disconnect the wires to silence the sound.

Get in the car, make sure your dome light is set to door-operation.
Close all the doors, does the dome light go out?
If so, it's not the door ajar chime. If not, one of your door pin switches is defective.
Buckle your seatbelt, does the seatbelt warning light on the dash go out?
If so, it's not the seatbelt alarm. If not, it's the seatbelt buckle receiver.
The light warning works with the key off, so it is not that since turning the car off would not stop it.
Last thing it could be is the ignition key alarm.
I have seen a few malfunction over the years.

It might be the seat belt receptacle.

check the sensor inside the seatbelt anchor.. it's probably not contacting properly
