Is the battery in the right way around/correctly?

Either the battery is reversed or dead or not a 2032

If you scroll to the bottom of this page you will find self help.

Follow the instructions in this thread to diagnose problem. That’s assuming you have the correct battery and polarity.

Yes, car unlock and lock just won’t detect unless the fob is close to the steering wheel

Yeah I read that, but the resolution was that Toyota bought back his car since they couldn’t find the problem. Thread is 5 years old and this just happen recently when I changed the key fob battery.

Sounds as though you may have to reset it via the steering column. Changing the battery shouldn’t have caused that but who knows with this shit anymore.

Does your second key work properly?

If it works with the key fob close to the steering wheel then you either have a DoA battery, a wrong battery or an upside down battery, take your pick.
The fact it registers when close to the steering column and locks/unlocks proves this.

+1 on weak fob battery. Sometimes new battery is weak from sitting too long on the shelf

I’ve tried varies battery of all of the brands and no result. Not sure if I should hard reset the car by unplugging the battery

where’d you get your batteries? Amazon or a local homedepot with known supply chain.
