If you car doors don’t work – don’t just rely on your remote. If your remotes stop working, the vehicle battery goes flat, or you lose your car keys / lock them in, then the only way into the vehicle may be by smashing the glass. An auto locksmith may not be able to help you.
If the locks are broken and the vehicle is deadlocked then no amount of bending the door open to poke something in in the gap is going to get you in. You can’t open the door by sliding a tool between the glass and the door. You are left with 2 choices – either go through the skin of the door, or break the window glass.
I’ve been to two Ford Transits and recently with faulty locks and the remotes couldn’t be used. The cheapest option was for the vehicle owner to smash their own glass. If you are going to smash your glass it’s advisable to completely tape the entire window up to prevent a mess like that above.
In one of the Transit examples it was the second time in 6 months the owner had to smash their own glass. If only they’d got their locks fixed the first time around.
