Toad alarm help please

Hi guys. so the Toad alarm/immobiliser on my Supra apparently has kicked the bucket. When I unlock via the fob, the car unlocks and the dash light illuminates green, but I get a single click from the motor and it doesn't do anything. This has been intermittently happening for about a year, but I've never really thought much of it, as I thought it was just the battery in the fob, so I would press unlock again and it would allow me to start the car. Now however, it's not starting at all.

I spoke to a local alarm specialist and he said it's a sign that the relay inside the immobiliser has failed and it will need to be replaced for a new unit. Does this sound correct?

If so, is there anything that I can do, to at least get the started to drive it to his workshop, or will it be a recovery truck jobbie?

My Toad alarm on the NA failed in late 2020 too (it was fitted in 2003); it basically wouldn't respond to the keyfobs anymore and if it did it was very temperamental about if it wanted to disengage the immobiliser or not. I paid a company to fit a Cobra one to match the one in the other car (and it has been perfect since, knock on wood!) Your symptoms do sound slightly different to mine as mine always started when the light went off, but they're probably right, as long as everything else is all good (keyfob battery, fuses etc.)

Maybe you could jump the starter motor and get it going that way (if the immobiliser will let you)? I probably wouldn't go beyond that though, better to be safe than sorry IMO.

Alternatively, you could have someone come out to the car and sort it (that's what I did, while I was WFH). I used https://www.autodefence.co.uk, and it was £420 fitted for a Cobra 4138 and a tilt sensor and I had/have nothing bad to say about the whole experience, so I'd recommend it personally (granted, it costs more to have them come to you).

Anyways, hope you get it sorted soon, I despise alarm issues!

So in the end it turned out that my alarm was fine - it was the starter motor 😁

And FML what a horrid job that was to swap out. The upper bolt was just a generally very painful experience. Got there in the end though and we're happy - we have a Supra again. Thought I'd share in case it helps anybody in the future.
