I thought I followed the instructions correctly, but have accidently engage the security system. Now everytime I open the door, the lights flash & horn blows for about 30 seconds, then shuts off.

Anyone run into this issue before? Any suggestions in re-programming the keyless remote without waking my neighbors again (10 pm now).

Neither of the 2 remotes I was trying to program works.

 

i was able to successfully program 1 remote, so I unlocked the doors ok.
