Cruiser how silly is this, we don't know if it has an alarm or not. We have never heard it cry out though. It does have an engine imboliser and the key needs to be near it before you can turn the engine knob (where a key would go). It is a "flash" system that uses a proxy card to unlock the car via a button on the door handle. If you don't have the proxy card closer than half a meter away from the button it won't unlock, so impossible to open the door. There is an actual key, I guess for when the battery in the proxy card goes flat (yes it really does have one). And I think somehow it is this system that is the reason that we still have a car. I really hope they can replace it as I've grown to adore it. I keep the card in my wallet. It has saved me twice already from loosing my wallet as both times I went from the shop to the car and the car wouldn't open, so back to the shop, picked up my wallet from the counter, and back to the car.
A lady at playcentre had the same car and system and I had to show her how to use it. She was using the silly little key that clips into the card.
Once she understood it, she loved it too
