Worn-out and exposed grounding wires found in the system, which aid in the closing and opening of the doors, can cause this problem, especially if one of the wires touches the body of the vehicle. This, too can make the doors to lock and unlock while you are driving.

Sounds like either an aftermarket alarm system set to automatically lock, problem in the drivers door wiring or bad lock switch. Time to start digging around and testing the wires. This does not sound like the common “shorted wire in the door boot” problem. Driver Door Module (DDM) controls only the LF door (driver’s).

Late-model Jeep vehicles have a feature known as “Auto Lock.” This feature automatically locks your Jeep’s doors when the gearshift moves from “Park” to “Drive.” When the gearshift is returned to “Park,” the doors automatically unlock. This setting is customizable.

Is this an MOT failure? It will fail if a passenger door cannot be opened from outside the vehicle using the relevant control. If the passenger door doesn’t open at all it will be a reason for refusal to test.

If you can’t open one door, try another door to see if it opens. If all of the doors remain locked, the issue may be with the remote lock or a damaged lock itself. In most cases, when a single door will not open, it’s due to a broken latch – which will require replacement.

Empty your boot of any unnecessary items and make sure your glove box is mainly being used to store important documents (OK, your trusty car sweets can probably stick around, too). This step might seem a bit basic, but examiners can actually refuse to carry out an MOT test if the car is too cluttered or dirty.

Nothing gets removed In fact, MOT testers aren’t allowed to remove any part of the vehicle they’re testing, so you can rest assured that your wheels stay firmly in place throughout. But even aside from clearly visible signs of damage, the MOT test requires a thorough examination of your car’s tyres.
