Try checking all of your fuses. Quite often a fuse blows when batteries or alternators are changed. There should be a fuse box in the engine compartment and another under the dash.

If it is solar powered and hasn't been used in some time, the battery may have died, permanently. If there is no battery to replace then it is broken forever. Sorry.When batteries are left without juice for a long period of time they die, and cannot be recharged.

You can't reset it yourself. It takes a scanner at your Local Dealership to do it. People do it, (new battery) everyday unaware that doing so can and usually does, arm the theft system and either kills the radio or the whole car. To me it's just another built-in defect that requires dealer assistance. It's a buzzkill I know, and it probably won't be long until car owners won't even have access to the engine compartment. They will need your VIN, and then they call HQ to get the code for your radio.

Check the pronges inside the battery compartment. They will be like copper plated if they are not loose or broken then it may be a motherboard issue.

after replacing the battery you had to reset it. short the pads inside your watch or push all the buttons of your watch at the same time

change the starter motor.
