Password not working after battery change

I replace the battery with a new ifixit battery but when starting the phone the passcode no longer works. I switched to the original battery and it works fine. I plan to change the settings so there is no password and try again but it seems like the device knows it is not a apple battery. Any work around or solutions. I will try to reseat the new battery one more time.

Is this a good question?

That's rather odd, never heard of this issue before. Remove the password lock with the old battery and then see if it works with the new battery

Never heard of this either. Please post your results

So I reinstalled the new battery and then received an error that the temperature is too high and the iPod need to cool down. Clearly there is an issue with the ifixit battery that I received.

Everybody makes mistakes. Maybe they gave you a bunk battery. Did this fix your problem? If not, did you try putting in the old battery? Pretty curious now

I reinstalled the old battery and the phone booted up fine. I contacted customer service and it sounds like the new battery is defective. They are sending a new one. I will try again and post what happens.

& what happened?

same exact thing. I was convinced I'd broken the connectors inside & got the over-temp warning because of that. anyway, the phone boots just fine (apart from the temp warning), finds 4G & wifi, but only offers emergency calls. full restore from itunes made no difference.

I will try the old battery again, though I can't leave it in the phone because it's swollen & has already caused the display to delaminate.

how the !&&* does it know it's a replacement battery? dear god, this is worse than epson & their printer cartridges that cost more than a new printer! :-/
