These issues can both be solved through programming. The crank time needs to be extended and the door locks (may) need to be set to double pulse. Can you unlock the doors by pressing the unlock button twice within one second?

Please read all the way through to familiarize yourself with the process before beginning.

Let's try the programming; you will need the vehicle key and the remote. The control/programming switch is located in the antenna on the windshield.

Turn the key on then off; press and hold the control button on the antenna to select the menu. One honk of the horn/flash of the parking lights indicates menu one(1). Now, press and release the button five (5) times (door lock pulses), then press and hold the button. While holding the control button on the antenna, press the lock button on the remote once. You should hear two horn honks/flashes from the parking lights. The system is now set for double pulse unlock. DO NOT RELEASE THE CONTROL BUTTON.

We will now advance to the third menu; release the control button, immediately press and hold the control button. After three seconds the system will begin to advance to the next menu. You will hear two horn honks/flashes from the parking lights. Continue to hold the control button to advance to the third menu. You will hear three horn honks/flashes from the parking lights. Now, press and release the control button three times, then press and hold the control button. While holding the control button, press and release the lock button on the remote. You should hear two horn honks/flashes from the parking lights. Two flashes/horn honks is .8 seconds cranking time. Release control button. Turn ignition on to exit programming/learn routine. Test the system.

If after testing the system , you require a longer cranking time; re-enter the programming/learn routine, menu three, option three and press the lock button on the remote once to advance to one(1) second cranking time.

The programming/learn routine exits if the ignition is turn on, the control button is pressed too many times or there is no activity for 30 seconds.

Start the laptop and press F8 to go into safemode. Once boots up, go to control panel and click on user account. There will be option to remove password or reset password.
Thanks

You should be pressing and holding the MENU button. Do you have one?

USE MENU 1 2 Mint AFTER its UNLOCKED

Most of the monitors have a function to lock the OSD to prevent accidental changes in the configuration of the monitor.
If you are constantly getting the message about OSD being locked and unlocked then it means that the OSD locking button is constantly pressed.
Usually it is the "Menu" button on the monitor which is used to lock the OSD.
Check if the Menu button is constantly pressed.
