Replacing battery in an '04 Explorer

If I replace the battery in an '04 Explorer, I am fairly sure I will
have to re-program the radio, but will I also have to re-set the
keyless entry security codes as well ?

Thanks

Go buy a memory saver that plugs into the cigar lighter and you won't
have to worry about it. It's a 9 volt battery connected to a cigar
lighter plug. Holds the memory while you swap the battery.
I have one that I made out of a plug and a special 12 volt photo battery.

Radio - yes.
Keyless entry - (if its factory) no.

I wonder why car radios don't use nvram for stations settings?

Went ahead and swapped the battery w/o a memory saver of any type.
Found one at the local Auto store, but they wanted $20 for a unit that
accepted a 9v as well as leads for another batter. Didn't do it, not
for one swap every 4 yrs.

Did not loose the security settings, did loose the radio stations,
clock and the trip-odometer.

Thanks

Trip-odometer is unexpected. Most cars preserve that.
