Why is battery picture shows on dashboard, - 1998 Lincoln Mark VIII

It means the battery in your key fob is low in charge and needs replacement. Once you know the battery number, you very likely can get such at Walmart. There likely is a video showing you how to open the key fob. This is much less expensive than replacing a key.

Charging system failure. Likely the battery but can be other.

Glow plug relay, or it's fuse?

Your battery are okay but you may have an alternator/generator problem, it's not charging back electricity to the battery. That's the common interpretation of that battery warning light on the dash...

sorry 2005 peugeot which is no doubt a europeon market model so the software used is encrypted as such and your ok if its a adelphi computer as a lot of profession scanners can reset the immobilisor but the newer the vehicle the less chance their is of unlocking it ,i paid 2500euros for a scanner/reader and i wasted my money ,So call the tow truck and have it taken to a dealer and smile when you get the bill ....

The battery and charging system is down. Have some one to check the voltage on the battery first without the cables off it. Then check it with the cables on it. If the voltage is below a 9 or 7 then change the battery. It may start up after you have change it if not, change both alternator and battery. you should be fine after that.During the summer keep you battery post and battery clean and free of dust and dirt.

bad key chip try another one or the dealer can make a new one aint-theft shuts the ignition down not reading chip or key

check start switch.

the light is across one diode in the rectifier pack in the alternator, usually there are 9 of them, one of yours has failed, probably the failed diode is leaking current and draining the battery. In this instance the battery will be good (if drained) and the other 8 diodes will show a good charge.Get the current drain checked with everything switched off

check your battery because if its deade your car may show diffrent alarms
