Alfa 156TS red fob programming
In a word - yes, but I'm not an specialist so can only tell you of my experiences. First of I have an AR 156TS 1.6 16v 2000 reg. Note that my car cannot be programmed manually (through the hole behind the courtesy light) or master remote as earlier models, or anything else - only by programming the receiver (via the ECU) to recognise the RF signal from the transmitter, i.e your fob. The fob itself is NOT programmed, it just emits a signal which your car has to recognise. I bought mine with one red fob only (the blade was broken and the guy had to order a copy, just the blade with immobiliser chip and no remote). The rubber button on the remote was missing and the seller said it wasn't working. I really didn't care since I was used to locking my old Polo manually for many years. Now that I wanted to sell the car, I thought I'd try to get it fixed. Before going to the locksmith I decided to to give it a go just for the hell of it and carefully pressed the tiny white button and it worked! The problem was this: if I use it to lock my car and set the alarm somewhere in the middle of nowhere - for instance, having strangled my boss and trying to get rid of the body - and then lose the remote or the switch comes off the PCB (they're said to be notoriously unreliable) I'd land myself in a tigh spot. So to get another copy of the remote (in your case - both copies) I had two avenues to explore: dealership or diy. The visit to the nearest dealership left me slightly shaken - £260 for a complete copy of the key (including the blade, immobiliser chip and remote). I wanted to say that I wasn't after another car, just a key... I found out that you can actually get your car's remote receiver to recognise up to seven red transmitters. I went on ebay and bought a red fob that came from 156TS of the same year. Now, I don't want ot mislead anyone but I think the markings on the blade have to match: 2 on one side and A602 on the other. The fob itsef has nothing written on it except 'ez', not sure if important at all and AR logo next to the LED light. The PCB is of rectangular shape. I spoke to a million auto locksmiths, phoned nearly every AR dealership in the country and was told exactly the same thing: it cannot be done and that's final. Some dealerships gave me an explanation: once the fob itself is programmed, it cannot be reprogrammed for any other car, and that you have to buy a completely virgin key to encode it for your car, which (see above) meant the dealer competely misunderstood the very principle of how alarm/central locking programming is done. A lot of posts on the net said the same. Anyway, I stubbornly refused to give up and kept digging and came across a feller - bless his soul, I owe him a beer truck load of fosters - who posted an article about red fobs on ebay. I got in touch with him (he's based somewhere near Notts) and he confirmed my suspicions - yes, it can be done and yes, the dealerships will be trying to get you to buy the new key and will tell you a load of nonsense. He advised me to tell them simply that my second fob was working perfectly before but then lost it code for some reason and needs to be re-programmed. I kept phoning around until I came across a Whitehouse Service Centre in Dartford (recently opened). They said they cannot be sure if it can be done but that they can give it a shot. It would cost me £50. It worked and I now I am in possession of two perfectly functioning remotes. Speak to Steven Lewendon. Note this only works for my model and I cannot vouch for any other. I just don't want the hardcore alfistas on this site to crucify and barbecue my *** because it doesn't work for their models.
All the above left me with just one other little problem. I have two remotes alright but just one key with immobiliser chip. I went to a specialist locksmith and had a copy of the blade made. This would open the door but won't start the car. And then I remembered that the native red fob (that the seller thought did not work) still has an immobiliser chip in it. I pulled it out and incerted it into the plastic housing of the newly cut key. Put it in the ignition - and bingo! It worked.
One other important thing.
In order to be able to re-program your alarm receiver (located right next to the interior light in the boot) you need to have a REMOTE KEY CODE. It has 6 digits. Has nothing to do with immobiliser chip security code (4 digits) or the blade code. You can get it for around £16 at your nearest dealership (they have access to the main database). You'll need to bring with you: logbook, id, proof of address and your wallet. I wasn't charged a dime at a garage in Bexlehead (can't remember the guy's name, bless his soul, he's guaranteed to go straight to heaven). I was mosly lucky I guess.
