With my Mazda 3, sport no less, I have suffered from a flat fob battery a couple of times, better to buy a new battery rather than one from the back of a drawer.
With mine there is a retractable key in the fob to gain access to the car and being a push button start the fob is held next to the button or even use it to push in the button.
There is a chip in the fob that the push button can detect, same as the type in your credit/debit card.

I have noticed while looking online to see how to start with a flat fob battery, quite a few people are realising the modern fob battery only lasts 2 or at best 3 years due to it having to 'talk' to the car all the time. Unlike our older Golf only draining when pressed.
And yes a new battery is best but you can keep and check expiry dates with the ones kept in the car.

The FSA licensed a twice convicted fraudster to handle our life´s savings. Guess what? He robbed us of £750,000.
