Car cuts out when starting up - immobiliser active on dash

[xsianxx]

Hi I've got a seat leon cupra 2016. Having an issue with it ever since I changed the battery in the key fob the car cuts out when I start it up - I've got a stop start error and immobiliser active message on the dash . Can anyone advice me on this?

Possible you damaged the glass immobiliser chip when opening/closing the key?

I had a locksmith do it so unsure - I don't even have a spare key either . I've just started the car now a couple of times and the fault isn't there only seems to do it now and then ?

Seems highly likely they damaged the chip, ive seen cases before where the chip is cracked and only works intermitantly. They are quite fragile, take it back to them. Most locksmiths can clone the chip onto a fresh one, hopefully for free given the circumstances.

So couldn he clone the chip and put the new chip in the keyfob?

Do I need to worry about my car cutting out during drive? I've drove it and it's been fine but never know

Yeah most locksmiths can. The chips are only a few quid, but you need the means to program them

Car will be fine to drive, the immobiliser only communicates with the chip when you start the engine. Once it's running it won't cut out even if the chip stops working
