If the op requests the thread removed I'll do do, if another mod removes it that's fine. Personally I'm not aware of thieves using old fashioned methods like this to steal vans, the vans get stolen digitally in minutes as far as I'm aware.
But since we are here then it is wise to disable or replace the drivers door barrel for added security.
Disable the diagnostic port of your van.
Tradesmen add extra security for anything you leave in the back such as bulkhead, extra hardware for cargo door locking etc.
Generally don't leave belongings visible in the front of the van.
Emergency services have used the wedge method for many years so it's very much information on the public domain.
Tibbe keys are well known for being easy to bypass also.
My suggestion also is to buy an extra alarm with loud siren to give an audible warning that someone is getting into your van, make sure it won't deactivate by unlocking the van but rather by remote or some kind of coding.
I doubt personally that opportunist and stupid thieves will be able to read this anyway
But yes let's try not posting how to's on breaking into vans on here.
