Friend has a dodge avenger 4 dr and has child safety lock enabled but cant open from inside or outside any way to get open ...... thanks

The Child Protection Door Locks (Rear Doors) are located inside the rear edge of the door. Insert the tip of the ignition key or similar flat-bladed object into the lock and rotate approximately one-quarter turn to the LOCK or UNLOCK position (as indicated by the stamped icons). WARNING!
Avoid trapping anyone in a vehicle in a collision.
Remember that the rear doors can only be opened
from the outside when the Child Protection Door
Locks are engaged.

Rinnai avenger 25 gas heater. Lock has been put on probably whilst shut off. Nothing works including holding down on/off for 3 seconds or turning off for 1 minute.

To deactivate the lock feature, press the up and down temperature buttons simultaneously for 3 seconds. The lock indicator will go out to show that the lock function is no longer activated.

Hope this helped you and thanks for choosing FixYa. Cheers

I have an avenger 25 plus it is showing the locked signal. how do i unlock it as i have lost my manual thank you

If you press the UP & Down Temperature Buttons simultaneously for 3 seconds, the unlock feature will unlock. To lock it, do the same thing.

For future reference, I have included a link to your Owner's Manual that you can download and print for future reference. Ater doing so, please keep it in a safe, accessible place.

Hope this helps you to stay warm, this winter.

Rinnai avenger 25 wont switch on and has a key symbol displayed

O.K If it just the child lock that has been activated then press both the UP and DOWN buttons together for 3 seconds. The lock indicator light should then go out. If there is no power at all it may be something more sinister.
