my horn and lights keep flashing on 2000 Chrysler Sebring , my remote doesn't work good, how d. stop horn and lights from flashing

Try changing the remote's battery.

batteries were changed, the electronic plate inside is worn ,it is 15 yrs old, we ordered a remote from the mainland , Chrysler. old not program it, luckily the company took back the remote, Chrysler wants $203.00 and $60 to program it

Put the key in the driver side door and turn it will disarm it

ours was opposite...unlock passenger side and it disarmed.
