@mozz smith is the king of getting these started when they throw a wobbly.
There's an LED by the windscreen and another on the gear-select lever and he'll want to know what they're doing.
As Marjon says, these things much prefer the remote, although if you don't have the generation 3 RF receiver that can cause issues like low volts, burnt out locks and loss of sync.
If you're keeping it then get a Nanocom rather than the one-trick pony Syncmate. And a proper key. And a proper RF receiver. And then turn off passive immobilisation.
