Replaced battery now Won't start

Was it the engine battery or key battery that was replaced?

Customer: replied 1 year ago.
Engine battery.. I do have a chip in my key which I believe has to do with the car not starting. I had to start it a particular
Way years ago after getting a new battery but I don't recall how
Expert:  Doug replied 1 year ago.

The chip in the key should not be affected by the engine battery being changed normally.

When you try to start the engine, it cracks but does not start, or does it not crank either?

If it cranks but doesn't start, does it sound abnormal (faster or slower than normal)?

I think it may be a anti theft thing from changing battery

There is a way to start ther car to read the cars computer I just don't know how
Expert:  Doug replied 1 year ago.

The vehicle has two factory security systems.... the immobilizer in the key which causes the fuel to cut if it does not match (and is RFID based, completely independent of the battery) and the wireless system that simply sounds the horn and lights when tripped. Neither should be impacted by the battery being disconnected unless there is an add-on module.
That said... to disarm it you would only either use the button on the key or use the key to unlock the drivers door twice. Those are the over ride measures for the factory system.

Do you have a second key you could try for comparison? Do you have a test light or meter?

Customer: replied 1 year ago.
The key I have is only for starting Bc it was never programmed for unlocking and locking
Expert:  Doug replied 1 year ago.

No problem, and no second key then I take it?
How about a meter or test light?

Customer: replied 1 year ago.
No second key and I'm not familiar with a test
Expert:  Doug replied 1 year ago.

I understand.

Lets take a visual inspection of your larger fusible links... these are the bigger fuses under the hood in the fuse box and specifically the one hanging off the positive battery post. Lets look to see if any of these are visibly broken (you can look through the window on the top of each). Also lets double check if you disassembled the positive battery terminal that all cables got reattached.
