One of my two 3TXA key fobs seems to have finally given up, but I do have one I bought on ebay (unprogrammed). I don’t want to send the Lucas 5AS, ECU and fobs away if I can help it.

I believe one option is to desolder the chip from my faulty fob and solder it into the fob I bought on ebay (desoldering that one first to get the practice, of course).

Has anyone done this? Any advice on the topic?

many thanks.

Martin

There are many places including independant garages & locksmiths that can program 5AS units in the vehicle - have you enquired locally?

(it's the 5AS you program, not the fob - if you find somewhere to do this you need to take all the fobs you want to use as the re-programming erases the previous settings)

Many thanks. I’m in north Manchester and every couple of years I have another go at trying to find someone within a reasonable driving distance but invariably draw a blank. I have tried autolocksmiths but have been told they simply do not have the equipment with it being such an old system. There was a place near Wigan but they got rid of their kit a while back. I’d only send all the kit away as a last resort, in case it got lost.

The 5AS was widely used in MG Rover vehicles including I believe late models of the proper Mini. Also in the Lotus Elise. Have you no local specialists for either of these you could ask? (maybe Mini Sport at Padiham)

Great! Thanks; never heard of them. I’ll ring them tomorrow and report back. Thanks for digging that out for me.

Update: I contacted Mini Sport at Padiham and whilst it’s been a long while since they did this sort of thing, they are prepared to have a go. They’re fully booked up until the end of the month. So, post MoT test, I’ll book a slot with them and see where we get to. Hopefully, I’ll remember to report back with an update.
Thanks again.

Update: I spoke to Kevin Wright, who’s just regassed 2 of my Hydragas units (07895 513800), he said to try MGFnTFBitz in Glossop, they were very helpful and in turn said to try Entune just a couple of miles from me near Radcliffe, and Entune said Horners in Swinton, just a few miles away, have the right kit. And indeed that is the case. Whilst the technician (Dave) said it’s a while since he’s reprogrammed a Lucas 5AS system to accept new fobs, he doesn’t see a problem, as long as the kit still works. So, all being well, that’s another problem solved.

Many thanks rqt.

I had a similar problem with my wife's Rover 25 but luckily I had previously bought a Pscan.uk diagnostic box for my Rover Mini and was able to reprogram the two key fobs. The instructions said I should wait for a beep from the alarm to confirm the reprogramming. As no beep was forthcoming I found out then that the alarm horn wasn't working! Up until then I assumed that the alarm worked over the car's horn! By the way the Pscan is great and well worth the 160.00

I don’t know why I haven’t come across pscan before. Perhaps it’s because I’ve been using the various MEMS Diagnostic software packages developed by keen Rover owners who happened to be good at coding. These various projects stemmed from Colin Bourassa’s work ( colinbourassa - Overview ). However, these packages are no use for the alarm or key fobs. Another reason I haven’t heard of pscan is that I’ve only used this forum when I’ve got stuck, and not as a matter of routine - something I need to put right.

So I’m really grateful for your opening my eyes to pscan. Even though buying pscan works out more expensive than one trip to a garage, I wouldn’t have the worry of turning up at a garage and discovering their kit no longer works or that the car ends up disabled through some glitch, or finding out that the fobs I bought on ebay don’t work and that another appointment would be needed. I’m sure you’re right: “well worth the £160”, From what I’ve seen on the website, it’s a very impressive and wide-ranging piece of kit.

Thank you very much for your advice.

Martin

Update: I got my pscan, and am very pleased with it. I have programmed 3 new fobs and my old fob, which really has a pathetically low range. It all worked out perfectly well. One very satisfied customer.

if anyone needs any pscan diagnostics or fob programming in the Greater Manchester area please PM me. I’d be pleased to help In any way to repay the help I’ve had from the forum.
