My name is chris I'm from california I have a 2013 lr2
it over heated and I replace the radiator and water pump with was a fun job but now there's a new problem I was trying to start it a bunch of times killed the battery got a new one but before that it went into immobilizer mode can some one help

 

So you should be in the LR2 forum not the freelander1 forum. AFAIR know, the immoblizer mode can only be cleared by, for sure, JLR SDD software/mongoose interphase or (?)maybe a GAPII tool. So that's likely the dealer or an independent that deals for years with LRs.
Also,go over to freel2.com and search "immobilizer mode". They should have you covered.

EDIT: A Hail Mary! Try a hard battery reset. Shut off vehicle, let it sit for 3 to 5 minutes. Disconnect the battery wires carefully, do not reattach, wait one to three minutes. Touch the positive wire to the negative wire for 10 seconds to drain all corrupted modules, wait 10 minutes. Reconnect the wires carefully to the battery! Wait ten minutes and then try starting it.....
