dashboard lights stay on and continuous beeping when key is out and doors shut

You have a battery drain, the dash lites you're talking about are part of it, is it the warning lites or illumination lites. If it's the warning lites start with the ignition switch, if it's the dash lites themselves start with the light switch. Batteries are not made to be discharged then recharged on a regular basis. They actually make a battery for that it's called a deep cycle battery.

thank you.. it's the warning lights.. like the battery, oil, fan fuel cap, etc.. there's also a continuous beeping.. I'll get my ignition switch checked.. greatly appreciate the quick response and help

Why does my desperate lights stay on after it's running

This happened with my daughter's 08 Mustang (V6) recently. There were other things happening as well. The radio also stayed on, and the remote wouldn't open the the trunk or activate the panic alarm. When I ran a diagnostic, no codes were reported, so I shut off the ignition, removed the key, and went to unplug the OBD2 meter. That's when the radio and dash light went off. Actually, the dash light blink on and off a couple of times. I realized that it was a wiring issue somewhere in the area of the OBD2 plug. Playing with the plug temporarily fixed the issue. I plan to remove the panels and try to secure the wires better. Also, an overflow of condensation or rain water in drain ports could be shorting out the wires, so I will check those as well.

S0, try wiggling your OBD2 plug gently, and see if that has any effect.
