From the outside, I use to be able to unlock all of the doors through the driver side door with a double turn of the key. Now it only unlocks the driver's door. I'm using a brand new master key that was cut to my VIN. 91 LS400. Anyone know whats up?

I haven't encountered this problem but generally troubleshooting
:
- have you tried it from the passenger's side?
- Is the battery fully charged?
- if you have the original key, does that work the same way ?

Check the key cylinder but that means pulling the door panel and checking the cylinder electrical contacts.

-Passenger side still unlocks all doors with one turn
-Battery is good
-Original key works the same way as the new one

Next up i'll try going into the door to check the electrical connections

Thanks for the tips
