Lost one of my keys. Any suggestions on how to get a replacement? I'm assuming the new OEM is a ripoff. Can I get a used one and have it reprogrammed?

Extra keys



I ordered 2 chip keys off the internet, and I guess I got lucky, because the locksmith I went to made them work.
He had just received the proper codes. He rekeyed my existing lone fob at the same time.
They were not push-button keys, but if you unlock twice, it doesn't set off the alarm.
I'm thinking it was under $100.
Good luck!

I've ordered a key for a 2012 500 Sport and a 2015 500e. First one I ordered straight from a Fiat dealership for about $180. Second one I ordered online for $160. But when I took it to my Jeep/Dodge dealer cause its closer than the Fiat dealer, they said they couldn't program it even though I was willing to pay them so I still had to take it to the Fiat dealership for programming. They cut the key based on your vin so you basically have to go through an OEM whether its a dealer or official mopar online.

It seems the risks are so high with not having a second key — and being sure that both of them have good batteries — that I will have to cough up. I want to make sure I spend as little as possible, and this conversation seems to have petered out. So, just to make sure: Can anyone give the name of a Fiat dealership in Southern California that gouges people less on this? OC Fiat charged half what the LA dealerships were on a pre-purchase inspection. I’m hoping it might work that way with keys, too. OC Fiat wants $280 per key. Does anybody beat that price? Secondly, did anyone have any recent success with Ace Hardware or any other locksmith in getting an infallible key, purportedly at 60% dealereship rates? Thanks in advance.

One of the laughable things about any serious probing on this is that these Fiat dealerships don't know their backsides from their elbows when it comes to pricing.
I joined up, buying a car, understanding that. I think the 500e is a viable car, certainly for the next 6-8 years, and I'm pretty sure I got one of the good ones.
These dealership guys, including a lot of their service departments, act like they're skedaddling tomorrow. I don't believe that. I don't think they can get away with that legally. I know I'm thumping my chest here, so go ahead and deflate me if I'm wrong. But from what I've seen in working this problem, I think they're going to have to come through with prices that are sane.
In other words, I think what I got from a lead tech yesterday, that he's worked for Fiat for more than a decade and that he expects to hang on for a few more years, does make sense.
We'll all do better if we all press them. So,a couple hours of phone calls showed that these dealers really don't know what to charge for a key. I got answers all over the map. I didn't divulge who was giving me the lowest offer, but I did say, "Hey, look. I have this offer from your competitor. Why should I pay more? Invariably the guy I was talking to started trying to dicker with me.
As a group, they're caving.
If you talk to a service or parts supervisor and press them on the prices they're asking, they roll their eyes. But they're car people. They know this isn't fair. They try to blame the capricious prices on Fiat and Chrysler. The fact is, they know it isn't fair, or even consistent. All of us should press them on what they're charging and why.

Consumer Reports did a good article on key replacement cost. For true "keyless" entry, it can cost $600 and up. The factory cost of a Fiat unprogrammed transmitter is $169. Add 20% dealer markup, plus the cost of cutting the key, plus 1/2 to 1 hour to program. Online you can buy that same key for around $110 from a dealer... $43 from 2012 - 2016 Fiat 500 Remote Flip Key 4B FCC# LTQFI2AM433TX

I think the few remaining studios might disappear soon. I don't expect my FCA dealer to drop his Fiat logo so long as the 500L and X are for sale... and will continue to service Fiats until parts are no longer available. (They also carry the Fiat based Jeeps.) The last time Fiat fled the US, parts were difficult to find, but not impossible, but dealers closed their doors over night.

Yes, generally it "has" to be a Fiat dealer. In your case, I'd price at your lock smiths first. I checked.

We have 3 lock smiths locally that can make an additional key. IIRC, "my guy" charges $120 for the key, plus $60 for programming... you can save ordering the key from Amazon. Those keys claim (and look) to be Mopar, but one is never sure.

He can't cut keys if all keys have been lost. He said the BCM is limited on the number of keys. I don't recall if he said if 3 could be added aftermarket, or a total of 3 (one extra). I think the reason he can't cut is that an existing key (for non-dealers) must be used to pull the programming codes.

He simply could not cut a 3rd key for my '18. Apparently the programming had changed, or maybe the FOB. (I didn't ask.)

I spend nearly a week sweating out the loss of my single Abarth Key but did find it. Checked with the dealer about making a backup. Got a lot of negative attitude (Criswell in Gaithersburg, Md) and was basically told it would cost at least $500.00 plus. (plus what?) Gawd help me if I ever lose this key again.

Sudaval, you are correct that some service centers will take all they can. I use a "trust but verify" system, especially for stuff like this, but my dealer usually has fair pricing. They do charge about 20% more than other locations, but they also keep track of all work done. That's nice when a part fails a year (or 8) down the road.

abenusa, when programming with AlfaOBD, it's a good idea to have a trickle charger on the battery. I don't know why, but the computer needs a full battery charge and peak voltage. (That's from guys who know the system better than I do.)

You can Google "Fiat 500 68091228AD". (I think that's the correct part #.) $110 is from Athens Dodge, but you would need to call to verify fitment, naturally. I'm sure they could give you the proper parts number, or call Fiat's national parts line. As you say, several countries make these replacements.

Don't buy a used key. As I understand it, they can't be reprogrammed, like we could in the "old" days.

Thanks.

1) I meant get a cheap non-transponder copy made just in case, so that after loosing your only transponder, you could open the door with the copy, alarm sounds, pop hood, disconnect 12V. Still possible BCM destruction?

2) In this scenario with one remaining transponder key, I guess you could just USE that one to start & drive, then always use cheap non-transponder keys to lock it in the car, hidden in the glovebox, under a cup in a holder, under a seat or mat, etc, etc, etc...

That's what I'm unsure of. Still stuck though because the car will never be started again without an authorized key and one has to have an authorized key in order to program new keys into the BCM.

I did that for a while before I got my second key. One advantage is that locking the car using a key doesn't activate the alarm system. But what I really was talking about was essentially permanently mounting the remaining authorized key in the car, then only using non transponder keys to turn the ignition and lock the car. This loses all alarm protection and makes the car more susceptable to theft. But a permanently mounted transponder is much less likely to be lost and non-transponder keys cost one tenth the price of properly programmed transponder ones.

Great! Thanks! So that's a solution IF you don't mind sacrificing security to save $280 on a spare transponder key:

If you only have 1 transponder key, to avoid frying your BCM if you lose that one, glue it inside the steering column cover & use cheap non-transponder keys to lock, unlock & drive.

One way to cheat is remove the chip from any remaining key and glue it close to the transponder reader inside the plastic shroud then from here on out you can use any abundant aftermarket keys non chipped or whatever to your liking. Only down side is obviously it’s easier to circumvent your cars security features but the way I look at it, if they want it bad enough they’ll take it anyway.

I broke my one and only key exploring this route. I made the mistake of thinking that the antenna was the transponder. Separating the two breaks the system. I was able to get some help transferring the chip from the broken board to an intact one fortunately.

My advice is to not remove anything and place the entire board in the steering column. The battery is unnecessary as it powers only the remote fob parts of the key. It is by far the cheapest way to get multiple keys for a 500e. However, the concerns are the loss of any remote functionality, and the above mentioned losses in security.

You have a single authorized fob which is disassembled and embedded into the steering column. So that fob is no longer accessible outside the car, right?

The transponder and remote functions are embedded into a single chip on an integrated board in the fob. Here's a picture of the board:
108592

The chip on the right hand side in the middle of the board on the left is the integrated transponder/encode/remote chip. The wire bundle at the top of the board on the right is the antenna for the transponder. Without a battery, this unit can still be read by the reader ring surrounding the ignition, but remote functionality is disabled.

So essentially this entire board would need to be inserted into the steering column. Both the lack of accessibility and the lack of battery power effectively disables the use of this fob for remote functions once it's put into the steering column.

Yea but isn’t the transponder and remote keyless still separate systems, meaning you can program another remote to the car but just not the transponder portion of it. At least that’s how it is with Nissan and Toyota vehicle’s I’ve worked on like a consumer can easily program the keyless remote themselves but not the transponder portion even if the key is all in one design like ours. All I’m saying is if I embed the transponder I should be able to purchase couple of aftermarket keys that don’t have the transponder but has the remote fob electronics and should still be able to lock and unlock with a second remote. Not sure how fiat differs then all other makes in that regard.

Not on the Fiat unfortunately. As I posted in my real early post here Fiat uses a crypto system that's tied to the car's Body Control Module. No fob that has not specifically been precoded for the specific Fiat in question can be authorized to manage the car. With Fiat the two functions are tied together, where the transponder is authorized for the car with the key in the ignition and then the remote functions on the same chip are authorized at the same time.

Fiat keys are a headache that I researched and tested for 6 months. It literally takes about $1000 worth of equipment to precode and introduce a key, which by definition makes it not worth doing. Embedding a single authorized fob in the steering column is the only cheap way of getting extra keys as none of the cut keys need to be authorized. Short of that, spending the $300 or so to get a 2nd key from the dealer is the way to go.

It's exactly as I described. You will have to get a new Body Control Module installed and have 2 new keys cut. $1400 is about the right price for that service from the dealer.

This is why I posted the warning to never activate the alarm with the last key. The damage is catastrophic when the last key is lost.

While I understand the frustration of the payout, it is a security measure designed to make the car inoperable on theft without a valid key.

Search through "Fiat all keys lost." and you'll see the same discussion over and over. The BCM must be replaced and only the dealer can do it.

I hope you can get your situation resolved.

This seems to be a very important lesson, learned the really expensive way by some. ga2500ev or anyone else please correct any of the following:

If at any time you are down to only one transponder key & you don't get a backup for about $380, losing that last key will cost about $1400 + towing to a dealership.

To avoid those costs you could get 1 or more cheap non-transponder copies, glue the transponder key inside the steering column cover, & use the cheap copy to lock/unlock/start. The alarm won't arm, & it would be possible to hotwire, but a thief won't know that, so they'll probably already be prepared to just slim-jim & tow it (normally needing to pop the hood to yank a 12v terminal to shut off the alarm).

New to this forum (just picked up a used 2014 500e with one key). Two questions: 1) where can I get a cheap non-transponder key copy; and 2) couldn't I just use that to lock/unlock/start the car (meaning without glueing/taping the transponder key to the column)? Or does the car need some kind of radio transmission from the transponder to start along with the physical key?
