My view is the immobiliser is by far the most important security feature - alarm systems, be they for auto or property, have little or no value.
Property [Home] CCTV systems are a worthwhile deterrent but research suggests these systems only displace crime, they don’t stop it.
BTW Your typical villain wears a hoodie and police resources are too thinly stretched to follow-up footage of unidentifiable actors [Unless a serious crime has been committed].
Sadly your typical villain also carries a blade so if you have to, call the police. Don’t make the mistake of placing yourself in danger.
As to alarms;
Most thefts from vehicles are opportunist - don’t leave possessions in a car, especially anything shiny/valuable. An alarm wont deter a smash-n-grab or a theft from an unlocked vehicle.
Most vehicle thefts are facilitated by securing keys first and if they have the keys the alarm argument is mute anyway.
Key security is paramount, they should never be left in-sight - even in your own home. Crooks will happily hook your keys through a letter box if given the opportunity.
The security feature that bothers me is the keyless-go system - a feature I’d delete if it were an option - I deactivate keyless-go with a double lock press on the remote every time I leave the car.
Not saying those that are bothered shouldn’t follow-up with Toyota but from a quick look, their “disclaimers” would probably give the most inexperienced lawyer enough to run-rings around any civil action.
