Recently purchased a 147 ti lusso and now have my first alfaism.
The unlock / look door buttons wont work of the fob (3 button remote with no led light)
The boot release button still works, the indicators on the wing don't flash and there is no audible beep from inside the car when the fob buttons are pressed.

Is it just a change of battery in the fob or does it need a ECU reset, any help appreciated

I have the same issue on mine. The car is programmed to the key which is fairly complex and requires specialist equipment to do the immobilizer. It's less involved to program the remote key fob to unlock/lock the doors. This does however require you to know what the alarm code is.

1. You have the key code and alarm code card with the car
I think they are two different codes, may depend on year, I'm not sure. They might be the same. Either way you need a code.
a. Get Multi ECU Scan (MES) and program the car to the key yourself. It will prompt for the code which must match what is in the Body Computer.

or

b. Take the car to a decent Alfa Specialist and they will program it for you (but you still need the code!).

2. Speak to an Alfa Specialist/Dealer and ask them to order the codes from Alfa.
Note: If the ECU or especially the Body Computer has ever been changed (ECU failure was an issue on these cars, so I suspect many have) they may not hold the correct code any longer.

I've still not resolved mine as the code I have doesn't work, so next step is to order the codes from Alfa and go from there.
You have to go through a similar process to add a new key to the car, but this 100% requires a dealer/specialist.

If the code I get from Alfa doesn't work then it's basically a case of new Body Computer / ECU and matching keys. Total pain in the bum really.

I assume the key opens and starts the car OK, so that rules out an immobiliser problem. The immobiliser is passive RFID, dependent on seeing a chip in the fob that works whether powered or not. If it does, then the question is whether the fob is defective or the alarm and door locking. NB If you dismantle the fob or replace the casing DO NOT LOSE THE SMALL IMMOBILISER CHIP. It's expensive to replace and the car is unusable without it. Take it apart on a white towel.

Fob: have you changed the battery? Easy and an obvious place to start. If still no good, the fobs very frequently suffer from defective button switches.

This eBay repairer is an AR member and his repair service gets positively mentioned quite often hereabouts.

Alarm and door locks: check fuses. In fact check battery connections and the state of the car battery too, low volts are an invitation for Alfa poltergeists. I've even seen a forum post that said simply disconnecting the battery for 15mins fixed not-working alarm & central locking.

Only then should you move on to more esoteric horrors such as mismatching keycodes or swapped computer modules. At that point you really need to get fault codes read to figure out what's going on.

Thanks for the information dudes, went to start the car today and now it wont turn over. The lights on the dash came on (odometer etc), but when I turn the key no engine noise at all. Also the manual key in the door will not lock the doors. So can't lock the car at all, good job I live in a quite area I suppose! Is this looking more like a dead battery now?

If you have another car with a good battery or a helpful mate with jump leads that's where I would be starting. Or call the AA! Good to rule out the obvious and potentially easy fixes first. Also check all the fuses as halftone suggested.

Good thread here covering the fuses: http://www.alfaowner.com/Forum/alfa-147-156-andamp-gt/202847-147-electrical-issues-fuse.html

I'm not 100% sure on this car but on previous alfas the engine will turnover but not start when the car has an immobilizer issue, it just cuts power to the fuel injectors. So it's unlikely to be that based on what you've said so far.

My money is on the battery. Do an ECU reset once it's all sorted.

If it is the battery consider why it's gone flat. Is it really old, is the alternator working correctly etc.

Swapped battery over this morning and the car started first flick! Key fob functions work also, so a knackered battery. Thanks for the help guys :thumbup:

Well done, your first Alfaism conquered. They go a bit bonkers with low battery. It's the petrolhead version of Snickers.
