Me...
I have an Autocop remote car locking system. I actually didnt require any more security systems as it is parked normally in safer places like inside the house at night and in the office parking in the day. for Esteem I have the same Autocop security system and a gear Lock from Autocop. its a pin type lock.
In both the cars the Remotes for the Central locking have been changed three times in the almost two years as all the remote buttons are normally getting bad after being used for every 6 months... I dont think its some fault from the Autocop's manufacturing but its the higher usage ofcourse. But they do have a wonderful service to get these replaced every time.

Autocop A5600 for Indica: Rs 3100 with 2 remotes + 3 yrs warranty

Autocop A5650 for Esteem: Rs 3300 with 2 remotes + 3 yrs warranty

Autocop Pin type Reverse Gear Lock: Rs 800 with 5 yrs warranty

i would rather say the central locking system is just for the convenience to lock and unlock all doors making keyless entries and exits. Yes as Zappo very correctly mentioned that the Central locking system is all gone when somebody makes the connection short by playing with wires below the left indicator near the battery, so a gear lock is more effective and useful.
