Title: Central Locking
Post by: Sharpshooter on December 22, 2005, 19:45:27
Hi All. I have a problem with the central locking on SWMBO's Disco

Its a 200Tdi on a J plate.

It has an aftermarket LASERLINE alarm fitted, which also has taken control of the locks.

When you lock it, all the doors lock, except the boot.

When you unlock it, only the boot and the drivers door unlock.

If you use them alot in any day, I.E. shopping, getting in and out alot, the others slowly start to work.

Is this a common prob, and how do i fix it??

All help greatfully recieved. :)

It almost sounds like the 2 wires to the boot solenoid are reverse.  However, the fact the it all starts to work after lots of use clouds matters.  It could be that a diode/rectifier is dying somewhere.

Can you disable the alarm and try the central locking with just the key?

i had a similar thing on my old 200tdi i took all the door cards off and wd40,d everything which cured it, the pivots on the linkage get dry and stiffen up and provide resistance which makes the system mess about

same here, the drivers door was the problem. you could do it by hand or thje key, but the solenoid hadn't got enough umph. so wd40'd it and works a treat....... for now :lol:

Try locking and unlocking it with the key for a couple of days.  If it behaves itself with the key you know the alarm is the problem.  

The system on the series 1 disco works through an orange and a pink wire.  The current is reversed to lock and unlock.  for example orange positive pink negative would lock it, orange negative pink positive would unlock it.

You could trace the wires from the alarm to these orange and pink wires and test them with a multimeter.   I am not familiar with the laserline alarm but you might find the central locking system part of it runs from the alarm to a relay then to the central locking wires, if so check the relay too.

Disconnect the alarm from the locks, nothing but trouble and with a sniffer/transmitter the scrotes can capture the code, wait for you to walk away and unlock as well as disarm the alarm.

Add to that the MOD's use of 433.920 Mhz jammers (lots of reasons, all legal, its THEIR frequency band) causing problems with alarm remotes (new renal's without keys only fobs it means locked out if they switch one on nearby).... :wink:

I'd go with the stiff linkage but before you start ripping door cards off try and make life easy. Just sit and pull the drivers door button up and down lots and lots of times, it may just clear some much out and what have you got to loose with it?
