96 bighorn. central locking not working

[1996bighornlotus]

hi all, just brought car and central locking doesnt work, (even tho it was advertised as working) cleaned and changed battery in the remote, seems fine. (any ways or tricks to test it?) still wont work, im after some trouble shooting ideas and locations of the central locking components in the vehicle so i can check them all out. any ones help is much appreciated!!

Check the fuses below the steering wheel to the right

does it work from the key? The drivers button and both door locks should lock and unlock all doors. I dont think these had remote locking as standard so its after market and likely to be part of an alarm system.

oh ok! yea locks with key and buttons on drivers and passengers door. have a remote thats got isuzu written on it so i think it was fitted with keyless entry. fuses are good, whats the next step?

Hide it in the glove box and forget it exists
There will be a solenoid and sensor somewhere but it will likely take an auto sparky and $$ to fix

battery?
