I can not close my front door. it appear that the half circle locking part of the door, which is located on the side of the door that opens, has a piece of medal that is blocking the door from closing. I tried to push the medal up and down but it will not move, The piece of medal is appears to also be a have circle.

Service repair info. manual would be the place to start ,seeing how you have no clue .,or maybe a qualified repair shop. How are you going to fix it with out knowledge of how it works an what to check , --------------------------------------------------------------------------------
Power Door Locks Circuit Description
The power door locks are operated by reversible motors. The motors are found in the following locations:
• In each front door
• The side door
• The rear door
The PWR ACCY circuit breaker (30A) supplies voltage to the door lock motors.
If you move either power door lock switch, mounted in the front doors, the LOCK applies voltage to cavity F of the door lock relay. This energizes the lock coil in the relay. Current then flows through CKT 295 (GRY) directly to the following components:
• Both front door lock motors
• The side door lock motor
• The rear door lock motor (cargo doors only)
CKT 246/294 (TAN) provides the ground for the motors. The normally closed contacts of the UNLOCK then contacts the door lock relay.
If you move one of the door lock switches to UNLOCK the polarity of the system reverses. Current flows through the energized UNLOCK relay contacts. The LOCK relay contacts provide ground.
When the UNLOCK button is pressed once on the RKE transmitter, only the driver door unlocks. If it is pressed a second time within 5 seconds, all doors unlock.
If the side door is open, the side door jamb switch ground signal is opened/broken. If you move the door lock switch to LOCK while the side door is open, the following actions occur:
• The 2 front doors lock
• The rear door locks (cargo doors only)
When you close the side door, the door jamb switch closes. This closes the ground signal to the body control module {CKT 775 (PNK)}. A 5 second timer then starts in the module. After 5 seconds, cavity A4 connector C1 of the body control module supplies voltage to the door lock relay via CKT 195 (LT BLU). This energizes the door lock relay, which sends voltage to the door lock motors in order to lock the side door. Refer to Door Jamb Switches, Liftgate Strut Switch for a schematic of all door jamb switch inputs.
If the side door opens during this 5 seconds, the 5 seconds timer is reset. The locking pulse takes place at the end of the 5 seconds. Unlocking the door resets the 5 second timer in the body control module.
Use the following components in order to unlock the door lock system:
• The LH power door lock switch
• The RH power door lock switch
On vehicles equipped with cargo doors, the cargo door opener mechanically opens the door once the door lock system is unlocked. On vehicle equipped with a liftgate, the liftgate lock/unlock release switch (mechanical key) is added in order to serve the same function as the front power door lock switches. These functions locking and unlocking all doors, including the liftgate. Once the door lock system is unlocked, press the liftgate release switch in order to electrically open the liftgate and pull the handle in order to open the secondary latch.

Lift the door handle as if you were opening it

Hold the handle & use a round phillips to hook
& rotate the white door latch to the open position

Open the inside panel of the door by popping off the little white clips holding it on. The cable connected to the inside release button is either caught on something or has come lose. Check out this video - https://www.youtube.com/watch?v=MkC2OiOiE_U

Your problem is the door thinks that it is already locked and closed. You need have the sliding door unlocked, have someone pull the handle as if they were going to open the door and then use a tool to "Open" the latch that normally would hold the door closed.

locate and replace door control module

I'm not sure about the noise, but the jerking motion might be because your the center roller (located in the rear middle of the sliding door) has worn out and need to be replace. This is a will known problem.

Your problem is very hard to answer because 05-10 odyssey has so many problem with sliding door.

rear latch:
-door not to latch close
-door not to work

front latch:
-door not to open

lock actuator:
-door not to open
-door will pop when opening

window motor:
-window not to work
-door will only open half way

center roller:
-jerking motion when opening
-door kick back close while opening
-door kick back open while closing

Door motor:
-door not to work
-cause door to jam

good luck

probably a solenoid thats not opening or closing. you can get one from a junk yard. its located inside the door. if you cant install it, have a shop you trust do the work.

U need to replace the switch called a door ajar switch, it is defective and causing this problem, it is located in the front of the door opening it has a punger that moves in and out as door is open and closed. Here is a photo
