Long story attempted to make short about Vectra CDTi 3 button key fob.
- Main key fob open button damaged and stopped working, soldered on switch from spare fob (in worse state with only one switch clicking).
- Worked perfectly for a few weeks then when locking the car both front windows would sometimes open.
- Tried to see if some fault with fob circuit board and ended up damaging previously soldered open switch so sent to Jesel Motors (recomended on here) for refurb.
- Recorded delivery parcel burst open and only empty package delivered (refunded promptly and good help from Jesel though no hope of finding fob).
- Send for new switches and fob case on ebay and had local code people (should have used first) refurb scabby spare key.
- Worked intermittently, sometimes prefect for a day or 2 then no function at all. Always seemed to be transmitting using test sensor but car not always receiving.
- Bought 2nd hand fob on ebay for £8.
- Local people recovered security key code for me (never had it) but unable to programme in new fob and discovered a fault in module (environment not recognised?)
- Advised I could order a new replacement 3 button fob (£85 inc. programming) and it might programme in first time and all work well – possibility it won’t programme in and they have to clear module and ecu down. Not guaranteed they can reset and start from scratch without fault recurring then car effectively immobilised and need to get a new ‘sim’ board? £100 2nd hand?
- So I have 2 original key blades, one original fob, one 2nd hand replacement and the joy of tripping the alarm every time till I get the key in the ignition. Car always starts so no problem with chip I presume.
Hope some of this makes sense, my terminology is probably wrong so any corrections welcome. I’ve read most of the posts on here about fobs, re-synching etc. Originally spoke to Vauxhall main dealer but they are notoriously bad and the buck passing and confusing between their parts and service department installed no faith at all.
I suppose my questions are: FOB1.jpg
- From the photos attached including numbers can you tell if the 2nd hand fob I bought should have been able to be programmed into my car? (It was transmitting fine - I knocked one of the switches off when disecting it)
- The original spare key that had new switches soldered on had the part noted fall off. I don’t know if this was loose and may have been causing the intermittent communication problem – anyway I cleverly dropped and lost it and now the intermittent success of about 50% has gone down to about 1% though it seems odd it should ever work if this is a crucial part. The part noted is actually off the ebay key which I removed after removing the battery holder to see if it’s interchangeable.
- Any experience of clearing the module / ecu with this ‘environment not recognised fault’ and is it likely to succeed or leave my car garaged until a new ‘sim’ board can be installed - or worse?
- Can the alarm be adjusted not to go off every time I open with the key as I could probably live with that and not have remote central locking?
Moral of the tale – use special delivery not recorded. Currently going through compensation process to see if they’ll up their offer from a book of stamps.
