Hi everyone,
Would like all doors to stay locked when shift to P. Followed instruction on manual but it didn't work. What did I do wrong?

Manual says to close all doors, turn key to "on", shift to "P", then hold the door lock on lock position for 5 seconds. Tried many times but it did not work.

I had this problem until someone explained that the twit who set up the programming wanted 5 seconds and only 5 seconds. Holding the button down longer fails the process.

Yes, it's absolutely ridiculous, but at least it's one of the few things you can do without the dealer...

 

Thanks, finally got it done. That 5 seconds is crucial...

 

The 5 seconds is very important. I had to start the car, shift to neutral, then turn engine off (key to aux).

Then I quickly turned key to ON postion, while very quickly shifting to park. Then I VERY quickly pushed the LOCK button down for exactly 5 seconds (the 5 beeps at the start are exactly 5 seconds). Finally it worked!

I wanted mine to NOT LOCK, while the OP wanted them TO LOCK when shifting from Park. Glad I finally figured it out.

The other thing you can do is count the flashes of the : on the clock in the dash. Each flash of : is one second.

And yes, it's very picky about being exactly five seconds.
