Thanks again. I was browsing through All Data and came across something interesting concerning opening the door with the key when the alarm is armed. I quote "The alarm cannot be armed/disarmed with the key. If a door is opened with the key when the alarm is armed, it will be set off. This does not apply to cars for the US/CA/LA market which are programmed for the key function". Since this car is a US car, was purchased in Seattle, Washington, USA, it just might work if it's programmed to do so. I'm going to have her buy a key from the dealer and will see what happens. Thanks, RG
