- 2010 Lacrosse CXL
My 2010 Lacrosse only has one fob, so I bought a second one. It is an OEM fob but I am having problems with the instructions for programming. Note: My car is button start only.
I'm supposed to put the working fob in the cup holder and then use the new fob's flip-out key to unlock the driver side door five times within 10 seconds. At that point, a message should come up on the driver information screen.
I have done this numerous times and get no response on the information screen. Has anyone successfully performed this procedure, and are there any tricks that I should know about?
