How do i un lock my sound - Sony Str-k740p Radio Receiver

Pressing this button stops operation of other buttons.
"Locking" or "Un-Locking" is repeated whenever pressing the CHILD LOCK button. (For "Locking" or "Un-.Locking" press the "CHILD LOCK" button for 3 secs.)
When 'CHILD LOCK' is activated, pressing the other buttons would not work.

check for a short or a bad wire sounds like a bad conection check your conections

Do you mean network lock??

they have a primary and a secondary lock, the secondary lock pulls in when the spin selection engages

The lock / unlock button on the side slide it down.

i dont know about a e350,but on a f150 there is a locking relay behind the dash on the passengers side,just listen for clinking sound when you un-lock it.

sounds like control module for central locking and or security system mal function

Well, sounds like a trip back to the dealer to get them to correct what they did. Sorry.

I have had this problem take you drivers door put your key and un-lock from the out side with key (NO) then open the door push un-lock from the inside button and then set from you remote and it should set if not push un-lock then lock and then do the un-lock with the key. Let me know if that works. what my car did was locked from the inside and I had the problem were it would not work till I un-locked from the out side plus I had to go to radio shack and change the battery from the control.
Hope good happens.

there is a short or a signal from the un-locking switch that is triggering your locks.

you have a switch manually to lock and un-lock your doors, the unlocking circuit is making contact.

you can try playing with your switch to un-short the switch or open it up ang check it.


tnx 4 using fixya,
