The Kenwood KDC-MP335 is an aftermarket car radio that's available for many cars and trucks. The radio unit comes with a built-in digital clock. If your clock is showing the wrong time, all you need to do is enter the radio's clock-setting mode to correct the time and set the clock.------------------------------------------------------------------------

Kenwood is not OEM make sure the memory wire gets power all the time.

To start with, I would go to a different shop.
Somebody will have to determine if the no-start problem is fuel or ignition related. You will have to leave the car overnight so they can start it cold.
There are several parts that are involved with the engine starting correctly, and they each have to be tested when the problem occurs.
I would also make sure someone checks the computer for trouble codes.
As for the blower motor, they should look for a voltage problem and a restriction in air flow in the heater box.

have you tried to press/hold lock button for 30 secs.
the code changes everytime you use the remote so that only your remote unlocks your car,not everybody elses.the key has a code inbuilt into it so the car will only start with your key...(this is dealer programmable)

Any time the transmission goes into the limp mode, it generates an error code that tells what caused it to go into limp mode. It could be something as simple as a loose connection on a sensor for the transmission computer. The code would explain which sensor was sending the correct signal.
By restarting the car you are resetting the transmission computer, clearing the limp condition.

you should have the fuel system check over really good
