I'll check the door handles then next. All four handles unlock, but only drivers side handles will lock. Sometimes the car won't unlock though unless I use the key. Might be cause the battery is really low.
Had the engine running for 20 minites earlier then turned off. Had the ignition and fog lights on for 5 minutes without the engine, and the battery died completely. I recon could be a combination of battery drain and a few dead battery cells. Think it's gonna need replaced either way.
Thanks for the pointers
