Screenshot 2020-02-19 at 09.22.55.pngI have an old DAF 45 on a 2000 plate and have lost the spare fob for the engine immobiliser. Unfortunately there is nothing on the existing fob to tell me which company made it. Are there any experts who might know the brands of what immobilisers were fitted at DAFs at this time please? The fob is keyless and black and used to have a red emblem on one side.
Thanks
