Remote Fob and Keys
Quote:
You can get a key cut from any competent key cutting place but it will not allow you to start the car, only open the door / boot. One way around this is to tape a chipped key (or just the chip from a spare key) to the steering column, out o site. Basically, there are two separate "systems" involved: 1) the key chip which works with the sensor ring to allow the engine to start / run. 2) the remote fob which operates the door locks remotely and arms / disarms the alarm. The expensive part appears to be getting a dealer to programm a remote fob to "talk" to the alarm / remote locking. HTH

Amongst the garbled thinking on this subject, Turboboy has it right.
This is not quite the perfect solution but it's cheap. I've managed to get a working remote Fob, with foldaway action. I can only speak for my V70 MY1999 - I've two of these cars. Both ETM Denso no-cable throttle etc variants. Quote:

See atttached, thus I'm halfway there... ie Using the PCB etc extracted from my existing 20 year old fob, I've got a remote-fob which 'remote locks/unlocks' my car. It looks great... But not so fast - what Timpsons could not give me was a chipped key. Thus the 'cut' was able to start the car, but it conked 3-4 secs later. To start the car required my original factory key held tight against my Timpsons-come-eBay-special. Thus only with my now manky 20YO key does it work. Not good. Seems previous posts have it about right, the immobilser-ring, which sits around the ignition lock, needs to be very close to the factory chipped-key to start the car. Quote:
I reckon I'll move my immobliser ring up into the dash, hide my factory chipper with it, source a pile more Timpson's £10 cuts, and be done. Not best, but it'll work. Hence I can always get in the car, and swap-out 9472461 if need be. Yes I could extract the chip from my factory key, and put it in my 'eBay folding special' yet walking about waiting for the day when (not if) I lose it and the pile of woe with it - has gotta rank as very dim. If I read right, short of daft money with a Volvo dealer, there's no other way.

Anyway if you want to program a fob to a vgla unit it is possible if you have some method to read the eeprom inside the vgla unit and a DECENT elm clone (cheap clones cannot take a new ecu address).
