Useful parts inside of a functioning CO/GAS detector?

Hi Everyone!

Greetings from San Diego!

A little OT, I have a CO alarm that just started beeping with an “ERR” – turns out it is an End Of Life warning (throw it out, get a new one) supposedly for safety reasons since there is no good way to ensure it will keep working longer.

In any event, are there any particularly desirable parts I should scavenge from inside – possibly a small sized beeper for putting inside a potato gun projectile, and a small 3 character LED display.  It’s a KIDDE nighthawk CO/GAS detector made in 2006 (End of Life beep starts 7 years after it was first powered up, not after manufacture).
