Thank You Very Much for The Maintenance Required Light Info, as far as the flashing car w the key inside. I'm not sure what key we have? When we bought it it only came with one key so we tried to make a duplicate, which ended up not working because we later found out it needs a chip (or probably what I hear as the smart key?) If the light is supposed to be on (and normal) why does it need reset?

The Maint Reqd light blinks after 4,500 miles, and stays ON continuously after 5,000 miles. This is to remind you that you need an oil change. Give the info from you about your key, you do not have a smart key. You have a transponder key. Off topic, but, FYI, a Toyota dealer can program a transponder key for you.
Back to the Maint Reqd light. Here is how you reset it:
Turn the key on.
Make sure that the odometer reads "ODO", and displays the total mileage traveled...If it displays trip a or trip b, push the black button by the odometer to make the display read ODO.
Turn the key off.
Press and HOLD the black trip reset button until advised to release it.
Turn the key ON. (keep holding th reset button down)
Observe the odometer display.
you will see 5 dashes, 4 dashes, 3 dashes, 2 dashes, 11 dash, followed by five zeros, and the total mileage you started with will re-display.
Release the button.
Turn the key off.

Regarding the flashing light with the car & the key: This is the indicator to show potential theives thatyou vehicle has a sophosticated security system, and it CAN NOT be started by "hot-wiring" it. The flashing light is normal, and consumes no battery power. I hope that this helps you understand these two items better. Thanks for choosing FixYA, and the graciousness of a FixYa rating for my solution to you would be greatly appreciated. Glad to be of assistance; please feel free to call upon me anytime. Have a great day.

This is how to reset the alarm Roll up all windows exit the car lock all doors with the remote, then wait ten minutes, unlock the door using the key, that will reset the alarm. without remote I found this, have no idea if it will work, but worth a try!!

Yes, there's a fuse box inside the hood for ac but there's one more in another fuse box inside the car for the ac control. Check the one inside first.

Replace the Gas Lift on Your Car Hood

I think you should go for repair manual first for your vehicle after that it will be easy for you to solve the problem. Check the link may be you will get something useful here Best Manuals

Certainly it could be shocks - worn shock absorber valves can cause some horrendous noises on certain types of road service, though strictly the noise could be caused by anything and there is no point guessing - only a hands-on inspection will reveal the culprit.

There are no relays in this system. The door switches communicate with the drier door ECU. The ECU communicates with the body control module and the BCM toggles + and - to the power door locks.
