Check the battery voltage, it should be 13.5 V, kick the headlights on for a minute and see if this "load test" will be sufficient to crank it over.

Check the battery in your remote control while you have your meter out.

you know modern car batteries will stop taking a charge ten percent per year....so check the "knock-off" labels on the top of your battery to see how old that it is...buy a new battery~
