Why won't key come out of ignition with battery connected?

Go on youtube and put in how to reset your car key after renewing key fob battery good luck colin

check your battery connections then charge the battery over night then check the charging system

was the key stuck in the ignition before you change the battery? Is it the right key or it a fresh cut key

if the key will not TURN the ignition try spraying alittle wd40 into it ,just a quick shot then run the key in and out a few times .if it turns but won't
start check your battery connections ,may need cleaning and tightening.
if lubing ignition does not work you may need a newly cut key a twenty year old key may be worn out.see a locksmith or dealer

Is the battery dead? Check your battery condition and connections. Check your starter fuse from there. Check the connection to the starter then progress to the ignition side of the concern

the clicking that you hear is coming from the starter relay. sounds like your ignition starter switch or ignition lock cylinder is bad.

does it turn over or does it do nothing at all

See the small wire on the solonoid top of the starter body.. it might be disconnected.. if it is connected see the fuse. other option, If you have a ligth bulb connect one wire to small wire on solonoid and body ground second wire of your ligth bulb. spin the ignition key to start position if the light bulb does not light there is a cut wire from the ignition key to solonoid.

This sounds more like an ignition issue and not a starter or battery issue. When you turn the key if no power is being sent to the major components then that is a fault either in the wiring to the ignition system or the ignition system itself is bad and you need to replace the ignition
