Hi Ducky, my smoke detector has been beeping away last few days so think it needs a battery replacement. It looks the same as yours. I don't have a key for key slot and can't figure out how to remove the battery carriage. Please can you let me know exactly how you managed to do it? TIA
Hi Piggybucket, my smoke detector has been beeping away last few days so think it needs a battery replacement. It looks similar to yours. I am having a similar problem to yours - no key for key slot and the battery carriage. Did you insert anything into the key slot when you managed to grip...
