hit it with a baseball bat and then get a new detector
Hi. I work for a lock company. Yes, you can just change the key part, also known as the core but most places like Home Depot, Menards, etc. don't sell just that part. You would have to buy the whole knob. You might be able to go through a local lock company to just get a core.
Did you make sure the battery was installed correctly? If the battery isn't making proper contact, the smoke detector will still think the battery is dead. Another common problem is dust. Try vacuuming out the detector. If the unit still continues to beep, you may need to replace the unit entirely. Be sure to buy one that is compatible with your existing system if you have interlinked detectors.
