Do you smoke in the car? could be that the infra red sensor in the car (usually near the interior mirror) needs cleaning. I bought a Renault Scenic which had same problem, it would only unlock from very close to the car. After trying new battery in the remote I cleaned the sensor and never had any more problems. PS I assume you've tried a new remote battery?
Was the car battery disconnected before this central locking problem.Also is the central locking system operated by remote.If yes,then is the remote battery new or old.If the battery in remote is old then try with new battery.Also if the central locking is controlled by a push button in the car then it can be the problem with push button switch .The switch on driver side is got short.It has to be checked with meter to confirm the fault.Apply a direct 12 volt external battery to the switch and check if the central locking is getting done.Also confirm if you can lock the doors manually by using a car key.If you are not able to lock the door with key manually then its faulty door latch.But if the door lock and unlock manually with out any problem then this problem is related to central locking switch or the remote.
replace batteries in remotes,then with key unlock car/hold key over windows go down,wait 20 secs,then lock/hold key over,windows go up,wait 20secs, then using remote press/hold down the unlock button for 30 secs.you have just reset the alarm/immobiliser.if remotes/keys dont work after this,then take it to a dealer for a computer/key reset.
Insert a key in the ignition and turn from 3(Off) to 4(On) eight times in rapid succession (within 10 seconds) with the eighth turn ending in the 4(On) position.
The doors will lock/unlock to confirm that programming mode has been entered.
Within 20 seconds, program a remote transmitter by pressing any button on a transmitter. The doors will lock/unlock to confirm that the remote transmitter has been programmed. (If more than 20 seconds pass before pressing a remote transmitter button, the programming mode will exit and the procedure will have to be repeated.)
Repeat the previous step to program additional remote transmitters. The doors will lock/unlock to confirm that each remote transmitter has been programmed.
When you have completed programming the remote transmitters, turn th ignition to 3(Off) or wait 20 seconds. Again the doors will lock/unlock to confirm programming has been completed.
1.) from driver seat , close all doors. 2.) insert key into ignition. 3.) while HOLDING the door lock switch in the unlock position , cycle the ignition switch ON OFF ON OFF. 4.) release the door unlock switch , the doors will lock and unlock to confirm programming mode. 5.) press and HOLD the UNLOCK button and LOCK button simultaneously on one transmitter , after a delay of 15 - 30 seconds , doors will lock and unlock to confirm programming of that transmitter. 6.) repeat step number 5 for up to 4 remotes. 7.) turn ignition switch to the RUN position to exit the programming mode. 8.) test remote operation of each remote.

Enter vehicle, close and lock all doors.
slowly insert and remove key from ignition 6 times within 10 seconds. The tail lamps will flash to indicate original code has been erased. Turn ignition to the ACC position.
Press any button on 1st transmitter.
Hazard lamps will flash to confirm programming.
TO enter additional transmitters, unlock then lock the doors using the power lock switch located on the driver door.
Press any button on additional transmitter (up to 4 tansmitters total possible). Hazard lamps will flash to confirm programming.
open the driver's door.
Turn ignition off.
You must re-program all existing transmitters as this process erases codes from car.
