Hi my buttons on my stilo keys have stopped responding...ive tried changing the batteries but no difference..the little red light on the key also goes on with the push of buttons. My spare key still works,however my main set of keys dont..any ideas on how to sort this out would be appreciated,I called fiat but the wanted 45 quid to do a diagnostic check...rip off i think.

Technical Remote key buttons not workiing :-(
Had that with mine 
then I picked up a post from rroope sying that it was probably the chip inside of it thats packed in ..I was forever dropping mine and thats what did the damage so I gather:bang:

Just had the same thing happen to me.... blipped the remote to unlock the car, drove 5 mins to Tesco's, then parked up and tried to blip the remote to lock the car... LED flashes on the remote but nothing happens...
What's annoying is that the remote activates/deactivates the alarm, which doesn't work if I just use the key instead.
My spare remote works just fine, but I would like to know how a chip can go from working perfectly to not in 5 mins without me dropping it!
I'm going to call into a dealer and see what they say but I guess its going to be expensive to fix

You don't say whether you've changed the battery?
I've just checked my manual and am surprised that you can't activate/deactivate alarm with just the key like some other cars (turn left the right, etc)
I'd be inclined to strip the fob apart and give everything a clean then change the battery.
I would hope it would be as simple as a battery issue, but I have not experienced any symptoms of a flagging battery in the remote, such as reduced range. It went from fine to dead in 5 mins... I will strip it apart and replace the battery though, but I gather from reading another thread on here that you have to lever off the Fiat badge to get to the screw... hmmm they don't make it simple do they?!
Cheers!

When i changed battery on mine, I just turned the small screw which is inside the area that the key blade folds into, there are 2 small picture of padlocks. Then the internals just swivel out.
Never tried to open up the whole unit so ca't comment further, sorry

Re: Remote key buttons not working :-(
The battery failed on my fob a year back, I tried to unlock the car, the LED flashed quickly but nothing happened. I pressed the button to open the boot and that worked, I had my tool box in the boot so I removed the battery then refitted and the fob worked. The next day I replaced the battery and have had no more problems. As for stripping the fob down, I under stand from a previous post that there is a screw under the fiat badge on the fob.

Re: Remote key buttons not working :-(
i just replaced my battery in the fob, the car would still lock/unlock, but it gave up the ghost when you wanted to drop the windows, they stopped halfway down, (handy little feature that for getting the condensation off the windows on these autum mornings!). since changing it, no more problems

Well, I swapped the battery from the working remote into the bad one and still nothing.. the LED still lights up but it won't lock/unlock the car. So its not a battery issue and must be something wrong with the electronics inside. Bloody typical the day after my car goes out of warranty this happens lol. I will call into the Fiat garage tomorrow and see what they suggest.
Well hows about phoneing ypur local Fiat garage and tell them that one of your remotes packed up last week and see if they can help you . Incidently I fixed a remote with a similar problem with a remote for my mums seat, I just resoldered the chip inside and has been fine since.
. Incidently I fixed a remote with a similar problem with a remote for my mums seat, I just resoldered the chip inside and has been fine since.Hi Ali,
My post refereed to a Seat remote not Fiat but the passable causes of failure are the same. If one of my fobs were defective I would certainly try and repair it, after all I would have nothing to loose but might end up saving the cost of a new fob + programming. As previously mentioned there is a screw under the fiat badge on the fob. I would resolder around any IC's but this is not an easy job as the pins are very small and close together and that makes it a quite a specialist skill.

I use one of these,takes a second!,good for home remotes aswell

Are you sure that your windows were shot wen you locked the car using the remote, because with mmine the windows were not fully locked up and the car locked fine but wouldnt open when i tried tuse the remote key, but they eventually worked wen the alrm sounded as i used the key to manually open the car, and i was also able to deactivate the alarm with the key too

Did you know that holding the door lock button closes the windows providing the remote is working
And the skyroof - if you have one .

Oooo I hate immobiliser systems and alarms with a passion as you know. A secret switch always worked fine for me and deadlocks don’t stop anyone breaking the glass to get in. They're fine when they work but it's more often the owner that has paid dearly for a system that locks them out from their own expensive equipment rather than the thief who can get in real easy if they want to. It often results in huge bills and damage to the car in removing panels just to let the owner into their own car. Each car and each generation of cars seems to work differently. More complication means more things to go wrong. Sigh!
Anyway, to understand how they work is a help to understanding what goes wrong
ENGINE IMMOBILISER
First thing to appreciate is that there is an engine immobiliser code, this is etched permanently physically into the key and doesn't need batteries to work as the code is picked up -just like an identifying microchip in your dog, (you don't put batteries in your dog either, ha!)- by an aerial - a circular pick up ring around the ignition switch- and of course this stops the engine working by not allowing fuel and ignition electrics so your thief can't make off with your car. Have a look at the stamp on metal of the key, see the triangle? If it has 2 stamped on it then it’s a type 2 immobiliser and that’s dealer only compared to early Fiat type 1 immobilisers which were easily copied at Timkins keycutters etc. Mind you, there are cunning ways and means.
OK now
CENTRAL LOCKING
For this, when one front door is locked physically with the key in the door or push button on the door then all the other locks can be made to lock/unlock at the same time. Yea yea we know this but feet off the desk as I’ll be asking questions later
REMOTE CENTRAL LOCKING
Ok this is where we have the key fob with a transmitter circuit board inside with a crystal to provide steady frequency and a chip multiplier to alter the frequency. This needs batteries for power to transmit, more often on 433MHz. There’s a receiver box in the car to pick up the transmission. The signal that is received is sent to the body computer and if it’s happy with the signal it will open the appropriate doors via the central locking
KEY SYNCHING
The body computer has to be told which key fobs to allow and the Stilo can take up to 4 different key fobs
PASSIVE ENTRY
Here the CID of your key fob is picked up by sensors in the car so it senses you approaching and opens the doors and allows the car to start without a key as long as the key fob is present
SO WHEN THINGS GO WRONG
Like all telecoms, is the sender putting out? Is the receiver receiving? Can they communicate with one another? Does the body computer know to accept this frequency? Handshaking and happy? All righty then!
KEY FOB
The red led on the key fob tells you the battery is working and the circuit board is live but that’s all it’s telling you. It may not be transmitting at all. For that you need a receiver tester on that frequency. The key fob as far as I know isn’t adjustable at all. It just puts out a frequency and it’s up to the body computer to recognise it and be told to allow it
Anyway, I have no idea whether this works on a Stilo but it does on lots of cars. Open the driver’s window and sit in the driver’s seat. You put the duff key fob into the ignition and turn it to MAR. You are telling the car “This is the right key and I’m not a thief” as it picks up the engine immobiliser code from the key. Now with the good key fob, reach out and lock the car doors by using the key physically in the door
You have now locked the car doors and have an accepted good key in the ignition and ignition is on
The next bit is a hit and miss and I’ve no idea whether it works on the Stilo as you need an unrecognised, non functioning key fob to try it. Press and hold the unlock button on the duff key fob in the ignition for at least 10secs. You are telling the car “You know this is the right key in the ignition and I’m locked in so open up the bloody doors!”. Hopefully, this tells the body computer to accept this key as well from now on. Turn the ignition off and remove the key. Wait 5 seconds. Then try the previously unrecognised key fob to see if it locks/unlocks. It works on Renaults and Range rovers etc but I've no idea whether the Stilo will allow it
You have nothing to lose and it would be interesting to see if it works as it can only be tested out if you have a duff remote in the first place
