It would seem to me that the car would be more easily reprogrammed than the "key"... Not that the system designers would necessarily think the same way I do of course...! Wesley Both are true. The key is programmed with info from the vehicle, and the vehicle is programmed with the key's ID. The key's ID can be erased from the vehicle, but once programmed, the key cannot be reprogrammed to another vehicle. What would be the point? I fail to see the logic of it. I'm not saying you are wrong. |
have a negative impact on security of the system.

The responder has two batteries in series. I have replaced mine for a 2001 PT. They cost about $4 apiece at my local battery source. |

Similar to modern toll road tags, parking garage access tags, RFID price tags, etc. etc. The current keys include both the transponder, which needs no battery, and the remote buttons for the keyless entry, and that does need the batteries. If you buy the simple transponder keys there is no battery and it's smaller. |
Smaller- but still stupidly big. I HATE modern car keys with big fat
heads holding transponders or remotes. A simple brass key is SO much
more convenient and so much easier to carry on a keyring.

Doesn't make squat of a difference on my insurance, and auto theft is
just not an issue around here. Especially not our PT cruiser. Gimme a
key that fits in my pocket.
Besides, there's NO reason that a transponder/security key HAS to be as
big as a hockey puck. It could be much smaller, as is the case with the
keyless ignition transponders that fit in a wallet.
