I got a car and within one day the locks becamse unresponsive. The remote never worked but the manual lock by using the trunk female did. It would lock and unlock all doors. Now it is unresponsive as well as the lock button on my dashboard key. I have to press down the locks manually which I dont feel comfortable doing. I also do not know how to take it in and out of valet mode.
