Trooper water inlet cap

Hi, I have a 1993 VW Trooper and have lost the only key to the water inlet cap.  Does anyone have a similar vintage trooper and can tell me a key number for their lock or who the lock is made by?  It was a fairly generic looking key so equally if anyone is willing to share a pic of their key I might be able to match it to a master with a locksmith. Thanks!

I doubt you'll have much chance of success that way - the problem is that A/S changed the products that they used very regularly, and there's a reasonable chance that the cap will have been changed by a previous owner since it was manufactured, and there's a pretty low chance that someone else's key will fit your lock anyway.

And unfortunately the concept of a "master key" only works for locks that are designed to have a master key (e.g. hotel door locks). There is no reason why a water inlet cap would have been designed to have a master key at all.

So... it's probably best to assume that you'll have to get the existing one off and replace it. If my experience of something similar is anything to go by, that probably won't be very hard - I just used a sliding hammer with a self-tapping screw into the centre of the lock, and it pulled the lock assembly out of the centre with very little force required.

Having said that... I would definitely recommend having just one more try at finding the key - they usually turn up eventually!

Thanks for your thoughtful response Roopert.  I'm clutching at straws at this stage as have exhausted all avenues for finding the key!

I know it doesn't help, but you have my sympathy. Our Trooper came to us with no keys for the water cap, though in our case if was a bit less annoying as the cap itself was unlocked. Changing it was a bit of a pain because the "standard" size of cap available now requires a slightly different sized hole, and the fixing holes are in different places too. We had to fill the existing holes, and we had a vinyl ring cut to cover the marks around the new one - though I have to say it looks Ok now it's done.

You might have another annoyance, in that I ~think~ the older vans used Imperial sized hoses and the current ones are metric - so you may also have to devise some sort of adapter. Good luck!

Thanks for the heads up.  Kicking myself even harder for loosing that darn key!

Hi Aine
  I’m jumping onto your blogg. I’ve just purchased a 1992 vw t4 trooper. When I viewed it at the garage it had a lockable cap on the water inlet. But when I collected it this had been replaced by a screw cap. I’ve asked the garage if I could have the old lockable one back but was informed that it was broken.
  So my question is do any of the members know where i could get another lockable cap. Its the old style??? Or point me in the right direction. !!

Just G**gle lockable motorhome water filler cap and you'll find lots on Amazon and the usual leisure supplies websites, some described as 'universal', however I'd suggest going to a local caravan spares dealer so you can check and make sure it actually fits your inlet before purchasing.

Hi Roger. Thank you for your reply. !!
