I've had 2 Mazda 6's. Great cars, but the second one had keyless ignition, which I found really annoying. If I am leaving something valuable in the boot (trunk)

I've had 2 Mazda 6's. Great cars, but the second one had keyless ignition, which I found really annoying. If I am leaving something valuable in the boot (trunk) I want to try the door handle to check the car is locked. But as soon as you walk up to the car it unlocked. I would have to give the key to a family member and have them walk away first. Grrr.
