1st check that you have at least 12V between the battery terminals, so ensuring the new battery doesn't need charging

then try a reset where you disconnect both battery terminal leads and clamp them together for at least 10 mins to completely discharge any capacitors around the car and force it back to factory setting

before disconnecting the battery then ensure the keys are outside the car and the window wound down as sometimes the doors can lock when its all reconnected

theres then a key relearn procedure to follow

Repeat 3 times (11 minutes each)
Turn the key like you would to start the vehicle.
Than after it is done, leave it in the on position for 11 minutes.
Turn the key all the way off and wait 20 seconds.
Repeat same thing another 11 minutes than turn off 20 seconds and one more time.
When this is complete the theft lamp should be off.
This will learn the key to the module allowing it to start

No key. It's has a fob and a start button.

OK in that case

I'd still do the battery reset and then touch the metal logo of the fob to the metal surround of the push button start to get it to do the security check
