?? That's interesting.  I DO have a second key and it does work, but
of course I have to lock-unlock the doors manually.  

Car runs with a "chipped" key that has an electronic door opener-
closer on the key chain.

It also also runs w/ that second key  that has no electronic door
opener.

Does that mean that second key is also chipped?

Does that also mean that the immobilizer security system is NOT
disabled?

(I don't even know what an "immobilizer security system"
is.  I tried to look it up, and got this:

==============
A vehicle immobilizer disables a vehicle's system after receiving from
a vehicle security system two immobilizer control signals in
predetermined states. The vehicle's system is a necessary system for
the vehicle to run, for example, an ignition system or an engine
computer, so that the vehicle is immobilized when the necessary system
is disabled. The immobilizer includes switching and self-biasing
circuits that bypass the security system. Bypassing the security
system reduces the likelihood of immobilizing a running vehicle
because of a security system malfunction.

Can you restate this in language that my tiny mind could grasp?<g>
