My remote keyless entry does not open or lock my door on my 2005 dodge caravan, when I press the lock button the horn blows but nothing else happens. When I press the unlock button the interoir light comes and still no locks work. when I press the lock button the interior light goes off. Any idea.

“CUSTOMER LEARN” MODE This feature is only available on domestic vehicles or those which have a U.S. country code designator. This procedure requires access to at least two valid Sentry Keys. If two valid Sentry Keys are not available, Sentry Key programming will require the use of a scan tool.
The steps required to program Sentry Keys with two valid Sentry Keys follows:
1. Obtain the blank Sentry Key(s) that need to be programmed. Cut the keys to match the ignition lock cylinder mechanical key codes. 2. Insert one of the two valid Sentry Keys into the ignition switch and turn the ignition switch to the ON position. 3. After the ignition switch has been in the ON position for longer than three seconds, but no more than fifteen seconds, cycle the ignition switch back to the OFF position. Replace the first valid Sentry Key in the ignition lock cylinder with the second valid Sentry Key and turn the ignition switch back to the ON position. The second valid Sentry Key must be inserted within 15 seconds of removing the first valid Sentry key. 4. About ten seconds after the completion of Step #3 , the indicator light will start to flash and a single audible chime tone will sound to indicate that the system has entered the "Customer Learn" programming mode. 5. Within sixty seconds of entering the "Customer Learn" programming mode, turn the ignition switch to the OFF position, replace the valid Sentry Key with a blank Sentry Key transponder, and turn the ignition switch back to the ON position. 6. About ten seconds after the completion of Step #5 , a single audible chime tone will sound and the indicator light will stop flashing and stay on solid for three seconds and then turn off to indicate that the blank Sentry Key has been successfully programmed. The SKREES will immediately exit the "Customer Learn" programming mode and the vehicle may be started using the newly programmed Sentry Key.

NOTE: The Remote Keyless Entry (RKE) Transmitter will also be programmed during this procedure. These steps must be completed in their entirety for each additional Sentry Key to be programmed. If any of the above steps are not completed in the given sequence, or within the allotted time, the SKREES will exit the "Customer Learn" programming mode and the programming will be unsuccessful. The SKREES will also automatically exit the "Customer Learn" programming mode if:

1. It sees a non-blank Sentry Key when it should see a blank.
2. If it has already programmed four (4) valid Sentry Keys.
3. If the ignition switch is turned to the OFF position for more than about fifty (50) seconds.

SOURCE: HORN WILL NOT SOUND BUT DOORS WILL LOCK WHEN I USE MY KEYLESS ENT

The title of you problem mentions the horn but the actual problem mentions the flashers? Which is it? You can turn the 'horn beep' feature on and off by simultaneously holding the lock and unlock buttons down on the remote for about 3 seconds or more. When the horn feature is turned on you will hear the horn, and when it turns off you will only see the lights flash.

I have had this problem take you drivers door put your key and un-lock from the out side with key (NO) then open the door push un-lock from the inside button and then set from you remote and it should set if not push un-lock then lock and then do the un-lock with the key. Let me know if that works. what my car did was locked from the inside and I had the problem were it would not work till I un-locked from the out side plus I had to go to radio shack and change the battery from the control.
Hope good happens.
