2005 Eventually it will start, no jumping required(yet)

Hello, so I have a 2005 with 176K miles. Lately, when I go to open the doors I notice that the locks slowly open & sometimes only the driver side door lock. I do not use the alarm and just use the inside door lock to save battery life. I have checked all the fuses, and made sure there are no lights left on. When I go to start the car, all the lights on the dash are lit, but the car will not turn on to the state prior to the engine turning over. After about 5 minutes of attempts the car will usually turn on to ready mode and act normal. the most effective method has been to get it into ACC mode & then push the brake before it will engage. Twice I have had no luck with this method or pressing the brake pedal then the power button and I have needed to disconnect the negative battery terminal to reset the computer. This has worked both times.

From what I can tell the battery has the power, but something electronically has gone wrong. I have not had to jump start it yet and the HV battery is more than 3/4 full and holding a good charge. No fuses appear to be blown either. Appreciate any thoughts. Original 12v lasted 14 years. Toyota replacement is 3 years & 3 months of the 84 month warranty. I only use the car for groceries and a couple of miles a few times per week to drive to our clubhouse. Thank you in advance.

Follow Up On intermittent starting challenges on 2005 Prius after using CTEK 5.0 4.3Ah charger/maintainer/reconditioner: Here is something puzzling? After reading the manual a second time, I decided to try the recondition option on the CTEK unit. After leaving it on until the 8 stages were completed, I unhooked it because all the lights on the unit went blank and headed off to the Toyota dealership to pickup a new battery. After returning home, some 10 miles later, I noticed that the old battery seemed to have started the car 3 times like normal. Feeling optimistic I set the car alarm(for the first time in months) to see what would happen with a small drain overnight. Low and behold it started up like normal and I was able to visit a friend. All I can think is that the recondition mode fixed something internally and the battery is holding a charge. It'll cost me a 20% restocking fee to return the battery, and I am holding on to it for the moment just in case this is a fluke.

 

Looks like the reconditioning mode on the CTEK worked! Thank you for your time Mendel. Have a great weekend.
