Repair Key Fob Vs. Buying And Programming A New One?

So I've had my Nitro for a couple years and I flippin love the thing. I've had a couple minor issues, nothing crazy (thankfully) but one somewhat superficial problem has been bothering me since purchase. A couple months after I bought it, I noticed that the unlock button on the key fob would not work maybe around 10% of the time. A quick shake would resolve the issue, and I didn't think much of it. When it started happening more and more often, I replaced the battery to no avail. It got to the point where the button worked maybe 2% of the time. One day, I finally decided to pop the sucker open and pretend I knew what I was looking at. What I found was that the small chip that gets activated when you press the unlock button had become detached from the circuit board, and the function would only work on the off chance that the free floating chip happened to be in its designated spot.

First off, let me just say that while I'm pretty tech savvy, I'm not very good with working with my hands. (I'm a social worker, I fix people, not stuff) My first question is, is it possible to use a small amount of low grade adhesive to secure the chip in place? Or will that just botch the entire unit?

The other option I've considered is replacing the fob. Now I'm not about to get bent over a barrel at a dealership to make this happen, so I've done a fair amount of research on what my options are, and the results have been....confusing. I've come across a fair amount of info that says you can just take the cut portion of the key, slap it in a new fob, and program the fob using a simple step by step process in the driver's seat. Other sites say I require 2 already programmed fobs for this, but as luck would have it, the dealership only received 1 key when my car was initially traded in.

Basically, what are my options here? I'd like to have a fully functioning fob, but not at a ridiculous cost. Sorry for the long winded opening, any input is highly appreciated.

Great details. Thanks for all the info...
Yes, you do need two already programmed fobs to self program a third.

EDIT: If you did not get an owners manual with your rig, you can download one for free from Dodge here.

If you move the cut key into a new fob, it will not work because the serial # from the original fob is contained in the electronics of the fob and is the one programmed into the system. Some key shops can copy the serial # from one fob to another, but the cost is going to be more then taking it to a dealer to and have the new serial # from the new fob programmed into the system. The dealer can also, at that time, remove the missing key # from the system. Which is a good idea since you don't know who has that key.

You don't have to buy a new key from a dealer! Costs way to much...

You could try a little epoxy to reattach the chip, unless it broke a solder joint, then it would have to be resoldered. I have not had my fob apart so I do not know how the contacts are connected.

Hi, No you can not glue it back inplace, can you post a pic of the small component, i think it is a SMD switch and most likly i can give you the repair method.

Sorry for the delay. Attached is the internal circuit board for the key fob. The small chip with the copper disc on top (on the right, its the one that's askew) is the chip for the unlock button.

Ok, this is a SMD switch (Surface Mount Device ), yes this is the unlock switch, if you are good with a soldering iron, then you could repair this yourself.
basicly it needs the four corners resoldering, however the solder posts are on the underside of the switch (not the four black spots on the top side), if you have a very fine soldering tip you can place the switch in place, and then just touch each corner with the soldering iron adding a small amount of solder, it is a delicate procedure, soldering iron must not be too hot and only a small amount of solder, or take to someone who repairs electronic devices, it is a 2 minute job.

there is a method using a very small heat gun but you must be experienced as you could end up desoldering other components.

Alright, thank you very much for the info. As I have zero experience with soldering (and fat fingers that don't do well with teeny tiny repairs) I will look to find someone that can repair electronic devices. I really appreciate the help.

Search Craigslist or local junkyard for FOBs. I bought a new unused key off Craigslist. I only received one original FOB with my Nitro. I bought a second key off Amazon. The second key was programmed by a local locksmith. After buying and keying the third key, I programmed it. I have three fully funcational FOBs. It's nice to have a third just incase I lose one.

Hey guys/gals,

I read that "You do not have to buy a new key from a dealer".... Okay, so where do you buy an OEM one? The "lock" "unlock" hieroglyphics have been rubbed off both my "from new" FOB's, and being that the one I still have is so old (8 years or so), it's starting to not respond and issue unlock/lock signals after I've pressed the button. I can still hear the lock/unlock system responding to phantom signals long after I stopped pressing any button. If I buy an OEM one then I have to have it cut too. The dealer quoted $260 out the door to get a new key/FOB and have it synched to my car. OUCH! But if I have to jump through 100 hoops to DIY, I might as well just go with the dealer.

I THINK, I have both (2), but I'll have to find the one I started using when getting the Nitro new.

(Only a pack-rat would hold on to something so old and redundant. Obviously Chrysler relied on that to sell, Sell! SELL!!! ...more parts.)

Google "dodge nitro 4 button key".
The back cover comes off the fob with a little prying. The battery # is on the battery.
I can't remember it off hand...
It does sound as if one of the buttons is sticking. Not sure if it is on the PCB or just the rubber is getting stuck. You will have to take it apart and have a look see.

As long as the 2 keys you have are still recognized by the nitro such as putting them into the ignition and starting the car.
You can buy n after market key on the intranet.
The one I bought came with instructions ( same as Nitro manual) to program the key to work with your vehicle.
http://www.keyless-remotes.com/?gclid=CNyRo8nswMwCFU6SfgodyVMLnw is one place.
All I had to do is get key cut and then let the Nitro do the programming.
Good luck.

Yea what those guys said...I got my keyfob key from Amazon for like 7 dollars... I have one factory plain computer key and then one factory keyfob key. I had it cut at the hardware store...they charged me for cutting each side instead of the one key...kind of silly... But when I got home I tried it and it cranked up and then dies because it wasn't programmed. Went to the manual and it tells you how so I programmed it in the driveway. It even programmed the buttons for me!

where do I buy a new battery? Does this sound like a battery problem (phantom signals. see above post), or is this a chip problem?
If you have a Batteries Plus anywhere by you, they will install the new battery for you. I like easy fixes. I also bought a spare key on EBay and then took it to my local locksmith, had to call around to find one that can program the FOB, and had an extra key made. Works great. I don't have auto start on mine, but I did not my R/T Charger and it had the FOB that is keyless. I bought an extra FOB for it and was able to program it myself and it worked great.
