Yes they changed them. Our 95 acts like your 93. The issue

is that if you open the driver door and the other door opens

it allows someone to jump in from the other door. That was

deemed a security risk. I think you can turn the key twice

to unlock all doors on the 97 (similar to pressing the unlock

button twice on the remote to unlock all doors).

I think there is a way to reprogram the remote on the 97

using some sequence with the cars' ignition key. Someone else will

have to post the details (I've seen it posted but don't know

what it is).
