The key fob no longer unlocks vehicle. When trying to enter car with key, the alarm goes off. Can’t start car because it is immobilized. Then when I try to lock the car with the key, alarm can take up to 2 min for the alarm to stop screaming!

Earlier today. The radio was showing “code”. I called an authorized Honda dealer and they gave me a code to enter to enable the radio after the car went dead when lights were left on. It seemed to work.
Would this have effected and somehow messed with my alarm?

When I push the lock button on the key, the horn don't blow nor does the lights flash. But when I hold the panic button the horn blows and light flash... also the horn itself works when pushed. Anyone know what the problem could b??
