Owners/service Manual problems of the 2016 Honda Odyssey

Car was parked in parking lot. I unlocked side doors and placed my purse with my key fob inside and strapped one 4 year old into one car seat in passenger middle seat and then another 4 year old in driver's side middle seat carseat. I hit the door close buttons respectively. I then went to open the driver's side door to enter and the door was locked. I then tried the slider behind me and that was locked, too. I walked around all the doors of the van and all were locked. The key and the preschoolers were all in the car. I coaxed one 4 year old who could get out of his car seat to climb up front to unlock the door manually but upon me watching the door would not unlock from the inside either. Her checked the passenger door which also would not unlock. I attempted to get help in the parking lot for someone to go into the store and get help but no-one came. The 4 year old on the other side of the glass was frantic as I kept trying to open all of the doors. I finally got him to get in my purse and was trying to help him, through the glass, to unlock the phone to call 911 when the car alarm enacted and although my car door still wouldn't open the other 4 year old managed to manually disengage the lock on the driver's side sliding door to enable me to climb through and start the car. No help came and I'm just grateful they were not younger and I wasn't hotter outside. The 4 year olds were terrified. I spoke with Honda service on the phone and the employee said it didn't sound electrical or mechanical and felt no need for me to bring my vehicle in.
