2001 freelander new battery but car wont start on key all lights come on on the dash but nothing happens wont turn over

Resetting the Passlock system should fix it. If it doesn't you need an auto electrician or an auto locksmith.

Battery is corroded, clean it and charge your Battery... Then see what happens...

A dead battery will not start a car

When this happens, move the Gear Selector lever a bit. It has a Neutral Safety switch that may be slightly out of adjustment

Hi Chris, Check the battery and terminals. Try a jump start and if that works replace the battery. Regards John

Sounds like the anti theft system is engaged.

I would have battery checked/charged and/or replaced. Then starter, then alternator checked.

Hi ShyFi,

I assume you've gone though the jumper cables routine?

You need to describe what it does do.
What happens when you turn the key? Clicks? Nothing? Dash lights come on?

What happens when you jump it?

Do the head lights come on? Bright? Low?

How do the terminals on the battery look? Clean? corroded?

Any recent events? Maintenance?

Comment back with the details.

Best regards,
Mike

when u turn on the ignition does the light for the dash board turn off and when u release the ignition key back light for dash board come back. If this happens a battery poles are dirty or loose try cleaning and tighten good

sounds like a dead battery to start with. Not even enough juice in the battery to energize the solenoid / brake interlock to get it out of PARK. Hope this helps

Do the dash lights come on ? They should come on when the key is turned to the on position. If nothing happens check the engine relay. It is not too expensive to replace if you really want to eliminate that as the problem. Check all wires going to the starter and make sure it is wired correctly.
