The push button led isnt lit and only the door opening button will work but the arming button doesnt do anything and the vehicle wont start as well as the oil light guage stays on?

It's supposed to off (sound the alarm) when the panic button is pushed.

Try disconnecting your battery (negative pole first and then the positive pole, wait 20 mins and then reconnect the negative pole first).

If the led is solid blue when the key is out of the ignition that means your in valet mode. Which would disable the alarm, but not the starter.
Simply turn key to IGN position then back to OFF.Push the valet button which is on the antenna next to the led and the led should turn off.Close door on vehicle and lock vehicle.Siren should now chirp.
Cheers!!

Similar just happened to us. Turned power off, waited a while, opened door. pressed and held power on button then pressed and held also the select button. Brought it back to life. End leds lit up and i could then select and worked when i shut the door. Ours is a smaller Renlig. Good luck.

Your system is in valet. To take the system out of valet with remote: open any door, press lock, unlock, lock. Now check the LED; it should be off. Close the door and arm the system to check.
OR
Turn the key on then off. Within ten seconds press and release the valet switch. The LED should be off now. Close the door and arm the system. The alarm should chirp to confirm that it is armed.

Your alarm got put into valet mode some how
.It's easy to reverse out of it back to normal. First look for a small black push button under the dash somewhere. It's called a valet button. Here are the steps.
1. open door
2.turn key on then off
3.then within 10 seconds hit that valet button once(your alarm light should be off. Tell you arm it again. Then it will blink)
Hope this helps

disarm system get inside the car turn key to ON position with door OPEN push the black valet button one time turn key off
now your out of Valet mode
or

open your door hit ARM then DISARM then ARM and that should also remove Valet mode if you don't know where the valet button is at.

You are in valet mode. It means the vehicle will lock/unlock but not arm the security system.

Open the door then hit lock then unlock and lock. Led will now turn off and work as normal.

Does the dishwasher work as normal? If so, most likely that LED burnt out.

Follow the following procedures for 2010 Ford vehicles with the door open shut down enabled:

1. Locate the override button and LED. On my escape the override button was at the bottom of the plastic by the driver's knees. The LED is attached to the harness behind this plastic, under the steering column. It is easier to find it once it's on.

2. Open the driver's door, press and hold the brake, turn the vehicle on.

3. While holding the brake, press and hold the override button, after 10-15 seconds the horn will honk 3 times. Let go of the button and the brake.

4. Push the override button until you hear the horn honk 5 times.

5. Push the brake until the horn honks 7 times, this is the "door open shut down" selection. The LED should be on.

6. Push the start button on the Key Fob. Do NOT hold it down, or it will reset everything.

7. The LED should now be off.

8. Shutdown the vehicle, and test it out.

Note: This procedure can be used to change the auto shut-off from 10 to 15 minutes as well. Instead of going to where the horn honks 7 times, go to where it honks 3 times, and turn the LED on.
