Did you try siting in the car, then lock/unlock from driver seat, see if the central locking mechanism working a not.

If it works, then i think the system spoilt since replacing battery also doesnt work.

got it for a few months.

inside car, locking is ok but braking does not trigger auto liao
after start engine, the warning for door open light is always on, although i check all door to be close properly. mayb 1 of the door spring is spoil?

alarm spoil go back agent get it done or outside better?

Try checking the remote...it may be damaged liao...my dad's 6month old sunny also got the locking problem using the remote control during the first 3 months of getting his car....TCM gave him a brand new remote....and it is ok now...
