I will assume you have a factory Anti-Theft system. Here is the rest procedure unlock the system which was triggered by the battery change and resultant loss of power. Do the reset exactly as written.

Put the key in the ignition, and turn forward
all the way just before cranking position. Then within
5 seconds, locate, press and hold in the
valet/overide button, found under the
dash area, (push button, spring loaded)
until the installed LED (the blinking light)
in your dash area goes on solid,
and the siren chirps once.

(Your valet switch might be the toggle
(on/off) type. in this case, key on,
flip switch in opposite direction,
then turn the key off.)

This should reset the alarm, and reset
the grounded relay on the starter wire,
allowing you to start the engine.

Hello Jaclyn...Look under the dash area for a button or, a toggle (valet)
switch. When you locate it, turn on the ignition key, press and hold in the button (little spring loaded micro button, red or black possibly)
until the alarm chirps 1 time. This should over ride the system, and only the keyless entry part, if installed, would still be operating....The LED light in the dash should also go on solid....At this point. the alarm would have reset.
If this had a starter kill relay installed it would now be opened, and the engine would turn over when tried.

You would repeat these steps to go back to user mode to see if this was corrected...i hope this information is helpful...Happy Holidays.

Remove the black battery cable. Put key in ignition (with battery unhooked) and turn to the on position. Replace the black battery cable with the key on and that should do it. If not, try locking and unlocking the driver's door with the key (with power on).

sorry this is a dealer fix. but it could be as simple as programing a new key.
