I have a 2003 Honda odyssey and my door locks lock automatically when I close the door I've been lock out twice running and without keys in it, Hope someone has an answer

For heavy machinery cars etc. luckily there are many websites
that can help you repair
for eg site like reliable-store is very active in this.. instant help, emails and all that's fantastic

Their is a power door lock relay that is probably going bad

try spaying wd40 inside the key hole with the little red tube that comes with the can

YES I HAD THE SAME PROBLEM I FIXED IT BY REMOVING DRIVERS DOOR PANEL AND FOUND ACTUATOR OUT OF LINE AND WIRE CONECTORS WERE BROKE I COULD NOT FIND REPLACEMENTS SO I USED WIRE ROPE GRIPS I ALSO FOUND LOOSE CONECTIONS IN WIRING I GOT CENTREL LOOKING WORKING AGAIN, HOPE THIS IS HELP.

Try to disconnect the battery for about 30 minutes this should reset the computer for you.

To begin programming, follow the procedure.

1. Set the following conditions: • Ignition off and ignition key out of cylinder. • All doors closed except drivers door. • Drivers door is unlocked.
2. Insert and remove the key from the ignition switch twice within 5 seconds.
3. After the above operations, close and open the driver door twice within 40 seconds. Then insert the key into the ignition key cylinder and remove it.
4. After the above operations, close and open the driver door twice within 40 seconds. Then insert the key into the ignition key cylinder and close the door.
5. Turn the ignition switch from LOCK to ON and back to LOCK at approximately 1 second interval 1to5 times to select desired mode. • 1 time for add mode • 2 times for rewrite mode • 3 times for confirmation mode • 5 times for prohibition mode
6. Remove the ignition key from the key cylinder.
7. After selecting a mode, the integration relay automatically performs the power door LOCK to UNLOCK operation within 3 seconds to inform the selected mode. • In the confirmation mode, when the operation is performed twice, it directs that 2 types of recognition codes have been registered. • In the confirmation mode, if the number of the registration code is 0 the LOCK to UNLOCK operation is automatically performed 5 times. • If the prohibition mode or confirmation mode is selected, registration procedure is completed. • If the add or rewrite mode has been selected, the doors will lock-unlock once or twice at 1 second intervals, once for add mode or twice for rewrite mode. • If the confirmation mode is selected, the doors will lock-unlock 0 to 2 times at 2 second intervals to inform the technician of the number of transmitters programmed. • If the prohibition mode is selected, the doors will lock-unlock 0 to 5 times at 1 second intervals.
8. Registering new recognition codes for the add mode or rewrite mode. • Within 40 seconds after the add mode or the rewrite mode has been selected, press the LOCK and UNLOCK buttons on the transmitter simultaneously for 1.0 to 1.5 seconds. Within 3 seconds after the previous operation, press either one of the buttons for more than 1.0 seconds. • Within 3 seconds after the transmitter has been turned off, the LOCK and UNLOCK operation will be automatically performed once if the registration of the recognition code of the transmitter is completed correctly. In case the LOCK and UNLOCK operation is performed twice, the registration of recognition code has failed. Perform the registration procedure from the beginning once again.
9. Press a transmitter button for 2 seconds. The doors will lock-unlock once at a 1 second interval to inform the technician that the signal has been received from the transmitter. • If the doors lock-unlock once, the transmitter programming has been completed. Go to step 8 to continue programming for additional transmitters. • If the doors lock-unlock twice, the transmitter programming is not complete. Go to step 8 to begin the transmitter programming again.

If any of the following conditions occur during programming, the remote control door lock receiver will return to normal operation:

Something similar to that was happening with our Odyssey...the beeping when you are driving whether it's ongoing or intermittent is the "safety alarm" letting you know the door is not closed. The power lock is not engaging. What I do when I get the beeping while driving is hit the Door Close button. It causes the door to attempt to engage again. To fix it...we first cleaned out the space below the side running board (kids were hiding crayons and things in there), then looked for any obstructions along the top and bottom tracks. I sprayed a lubricant along the tracks (I'd suggest the dry lube kind...I used WD40 the 1st time and had streaks of it dripping down after driving), use a lube that has a long straw to spray in small places...and spray up into the track that runs the length of the middle of the car. Manually open and shut it a few times to get the tracks lubed, then try it out.
If you press the open OR close button by remote or in the car and get nothing...no movement/no noises/no beeping...then it could be the electrical circuit itself, the signal itself may be impeded...or the motor shot. Have you tried any of these suggestions before?

this is your power lock actuators. both quit working at same time??

Have you tried using the key to unlock the door? I'm assuming you're referring to the lock mechanism. You can also try the remote (if you have one), click twice, it should unlatch and allow you to close the door. Let me know how you make out. good luck! countrycurt0

Multiplex is a small part which sends the on/off signal from the actuator to all the door switches.  It is a dealer part.  You may be able to fix the multiplex if it is a contact issue. Good luck.
