I got my keys re-programmed today (paid for by the previous owner

).
However, I notice the following difference.......
My old key - press the unlock button once = all doors unlock as normal.
The new key - Press the unlock button once = only drivers door unlocks. Press unlock button twice = all doors unlock.
Which of the above two is 'normal'??
I asked the dealer why they were different, and he said it was probably down to the second key being brand new?
I thought both keys should operate the same??
Im wondering whether they re-programmed the second key, and didnt do the first as well?? I needed both done!
