Does anyone have a solution so this won't happen again? My driver's door (right side UK) would not open. The key fob worked fine and all other doors open without a problem.
It was suggested that I disconnect the battery negative so the alarm goes off then put the negative back and try that..... I did this and the door opened!!
I've since been told it's a deadlock issue especially with the export Nitro. What I'm asking is, ....... Is there a fix so this won't happen again??

the way the locks work on the export Nitro (has additional security) is quite complicated, so to find a solution to your issue we need some more info, it could be a faulty lock mechanism, a broken wire, faulty TIPM (computerised fuse box), etc
but i'm pretty sure we can quickly narrow it down,
when all doors are unlocked and the drivers door stays locked, can you open the drivers door from inside the vehicle ?

No I could not open the door from the inside

so from inside the vehicle you pulled up the door lock pin, pulled on the door interior handle and still the door wouldn't open ?

I tried everything to open the drivers door.... Pulling the pin, trying to open the door from the inside, opening and closing the door lock several times with the key fob.... Literally everything! But nothing worked until I disconnect the negative battery cable.... Once I'd done that, the alarm sounded so I reconnected the battery cable and it worked... I could open the drivers door and it's still okay.

I've been told it's a common problem with the deadlock on all export Nitros

there is not a common deadlock problem, however you are not the first
there is a common problem where a door lock or locks stop working due to a burnt out relay internal to the TIPM (not serviceable, requires a deconstruction of the TIPM to repair), But 99% of the time when this is the case fuse M38 blows and instantly blows if replaced, and the rear window washer stops working, have you had any blown fuses or other electrical issues ?

I've had no other electrical problems whatsoever.
I've been told to cut the deadlock wire and that will sort out the door locking problem. It certainly seems connected to the security system.

I've also been told it's because export Nitros have extra security..... OEM security deadlock system??
To be honest I don't know, it's just what people are telling me

your info is correct, its just not a common issue, or at least not here on Nitroforumz, i'll post some more info tommorow then you can decide your next step (got to be up early in the morning),

When I say 'common fault' there's quite a lot of people saying they've had the exact same problem on several facebook Dodge Nitro groups....

I don't know whether or not it's an actual common issue registered with Dodge. (If that makes sense?)

I'm no mechanic so I really don't know

so here is a little more info regarding the alarm and deadlocks, keeping things simple: when you press the lock button on the keyfob, all doors lock, the alarm starts its 20 second arming process, after the 20 seconds the interior motion sensors and deadlocks are activaited, you can hear the deadlock relays activaiting if you listen carefully behind the kick panel in drivers side footwell, the deadlock system is a mechanism within the door lock which disables all electronic and mechanical parts of the locking system, so no matter what you try you cannot unlock the doors, not even the "slim jim" down the side of the window, it's virtually impossible, the elctronic side of the alarm system is part of the TIPM (there is also a seperate siren with it's own battery), maybe a Dodge specialist can disarm the alarm (not sure), as for cutting the feed wire for the deadlocks, not sure if this is a good idea never heard of anyone try it, i would have thought the vehicles computer would log it as a fault (again not sure), the vehicles computer will cut the power to a specific circuit if it detects a fault, disconnecting the vehicles battery will reset the computer, if there is an intermittent fault this explains why things work once the battery is reconnected
anyways after all that, the thing i would check for first is a broken or damage wire (wire rubbing on part of the metal bodywork) anywhere between the A-pillar and the door lock, BUT getting to the wiring harness is quite a large job to take on, and obviously i am just quessing at a solution based on your description,

hope this is of some help

Thank you for your very detailed explanation of the deadlock system...... I will look for the possible wire problem and see if anything looks likely to be rubbing against the frame or whatever is causing the problem...... However I have 'for now' cut the deadlock wire behind the door panel. I will keep a close eye on things (code problems) and post on this thread if it is working or not.... At the moment everything is okay.
