dilema

went out to go to town in the dually the other day...the doors are all locked. i never lock my vehicle doors! the key fob wouldn't unlock them, nor would the key work to unlock them. any ideas short of breaking a window? PfffffT!

Sounds to me like your Body Control Module is acting up. Only advice for now is to call a pro (AAA or locksmith) to get you going.

Could the battery in your key fob need to be replaced?

Aren't modern computer controlled vehicles just the greatest thing ever   Another good reason to keep my old things going. 

Call some of your law enforcement buddies or the local fire department. There should be a few "experts" in that crowd. The fire department could use it as a training opportunity. If you do decide to pop a window a sheet metal punch in a lower corner of the glass will do the trick. I keep my doors locked almost all the time, a habit I picked up from some of the areas I used to work in.

 I would suggest you put that ca boom stuff, tammeright or what every it is on the door. Been your helpful advice to others.  But since trucks are hard to get everybody is saying, give it another chance first. 

HOW ABOUT THE KEY ??  FORGET THE ELECTRICAL SYSTEM !

Since he has 2 different kind of keys, im wondering if the ignition switch died and they installed a new one... Then it has a different key than original ... Now the key dont match the door... Goes in the hole but will not turn.... You would think the TWO  keys that dont fit the ignition would be the OLD DOOR KEY ?

yea.... but if you NEVER used either for 18 years ??? ...... its possible  they FROZE ?

Entirely different situation but if there was a small child inside the local law enforcement/fire dept. will get if open one way or the other. They try the no damage approach first and if that doesn't work-good bye glass.

shameless my '03 Dodge has power locks and a keyhole on the driver's door only... Is that how yours is, and that one won't take either of your keys? I've never bothered putting a battery in the fob deal and just use the key since I have to have the key to start it anyways.

the truck is open...WooHoo! i took the fob to O'reilys auto parts, they have a machine that tells you if the fob is good or not (how? i dunno) anyways...they got it apart without breaking it and checked the contacts, said the battery was still good. they fiddled around inside the fob and put it back together. i took it home and tried it and the doors unlocked! double WooHoo! one of the other keys is the one that has the dealers ID tag with the info hand written on it, it don't do nuthin on that truck. the place i bought this truck at had another Dodge dually there, prolly belongs to it. no...i never thought about trying the keys when i bought it...just took for granted. funny on how we all forget little things when buying a vehicle. anyways...now i can drive it again. the truck is fun to drive, just gotta know where them back fenders are all the time! lol thanks ya'll for your imputs 

I added a KEY PAD to the outside of the door on my old 2002 FORD.. No wires involved.. It is basically a REMOTE like the FOB, but you program in a 5 digit code.. Bought it on e-bay 15 years ago !  Just double stick tape to the door.

Good that you got your truck unlocked Shameless!
