Battery has been changed in my winchester gun safe. red light is blinking. i punched in code and does nothing. no beep no nothing. what can i do?

read owners manual --notify winchester---or locksmith

Winchester uses several different brands of locks. You need to be more specific as to the lock that is on your safe. However, most batteries are contained in a housing on the under side of the code entry pad.

S&G batteries are usually removed by simply pulling slightly forward on the tab on the housing on the base of the lock. The housing will then drop down and you can change the battery.

Some locks will actually have the battery contained inside the code entry pad housing which can be removed by grasping the entire key pad housing and rotating the housing a few degrees counter clockwise, and then pulling the unit straight toward you.

Some locks may require you to remove a screw, but most do not.

A more specific description of which lock is installed in your safe will allow for a more specific answer. A picture also helps.

Get a new air rifle with more power?

If you can get the door open (which I've seen several procedures for), you can reset the panel with the red reset button on the inside of the door on the hinge side. It will beep and the orange LED will light up solid. Now you can type your 4 digit code, press B, confirm code, press B again et voila!

was there not a key also? if not then remove the new and start over, if it still wont open refer to your paperwork that came with the unit there is always a number to call for questions.

I had this exact same problem. Then I realized the red reset button was actually INSIDE the safe itself. So you need to enter the factory default code "159" to open the safe, then on the inside of the safe next to where the batteries are is a red button. If you press that, the yellow light will flash and you'll get two beeps. That means you can now enter your own combination. I hope this helps.

Motorola IC #MC68HRC705 will not reset. Chip is most likely bad. Time to throw this safe out...Thanks for your answers. George
