Central locking and keys

[dougieboard]

Hello all - long-time lurker!

I have two questions and I hope you can help - I haven't managed to find the answers by searching but forgive me if this has been covered. 

I got a well-used M49 Quiksilver Partner in Feb which came with two keys - one with an immob chip, the other is just a key - will open the door but not start the van. Neither has a remote. 

So, question one is should/could the van have had remote keys? Were they standard on M49-type vans? Or is there a VIN look-up I can do to see if I can get remote keys resupplied?

Additionally, I have an issue where I cannot lock the tailgate. The lock barrel appears to be jammed solid (not sure if that impacts whether the central locking will work), so I can't lock it with the key. But when I lock the cab door with the key, the doors lock, but the tailgate doesn't.
And if I open the tailgate, when I get to about 45deg, the whole van unlocks. Sub-optimal. The wiring sleeve in the top-left corner looks a bit chewed up so I will investigate that, but before I start pulling things apart, I thought I'd check if there is something that you have all seen before that I should be checking first to give these symptoms.  

Any help at all is much appreciated. 

Cheers

Hi there its hard to tell if you had remote keys originally it sounds like the second key was cut as a spare key but didnt have a chip fitted and coded to the car. A decent auto locksmith could do this for you so you have at least two keys that start the car incase you lose one. The rear lock could have siezed up or the linkage as well as when a remote is used the lock doesnt get lubed by movement. As you say check out the wiring first as it could be damaged.

Thanks for the comments. I'll have a local auto locksmith so will get a couple of new keys as the working one I already have has a nasty blob of Gorilla glue holding the case together!

I have my multimeter and have ordered a handful of new tailgate trim clips so will prise it off to have a poke around. I am braced for some sort of wiring horror show as the rear wiper motor has been removed - suggests to me someone has taken a bit of a nuclear approach to fixing some tailgate area wiring issues... 

thanks

Good luck come back and tell us how you got on. I know on that age of berlingo there was a change in the rear wiper motor wiring I think it went from 4 wires to 3 wires. So people brought a secondhand motor to replace their faulty one then found out needed a wiring fix so there are questions on here about swapping it. This could be the reason for bodgery to the wiring around there.

This has turned into a multi-part job. I got the tailgate trim off and got access to everything. The original lock barrel is seized up. I have split it all apart but it's rock solid so I have fitted a replacement - I can now lock the tailgate with a key, so at least my dog won't get stolen!

Still on the trail of the electical issues. Having to do some detective work first. The van has a lot of additional 'salad' as we used to call bundles of unidentifiable cables - it has had an aftermarket double-din radio, a elderly phone cradle and an aftermarket alarm so I am not sure which cables are for what. There is also a switch attached to the cabin fusebox lid. Too scared to press it in case it breaks something!

In the tailgate at least, I have two OEM-style plugs which are just hanging in mid-air. One is two pin with what looks like Gr/Yellow and yellow cables running to it and the other is four-pin and looks to be postioned for the rear wash wipe. Will get the meter on them over the weekend to see if they have any power.
