In the 2017 Toyota Corolla, the key battery is a CR2032 type. As you drive the vehicle over time, you may encounter issues with the battery. For instance, there could be a leak leading to fluid spillage or the battery could simply die. In such cases, you'll have to recharge or replace the battery. If the case of the battery cracks, it will need a complete replacement. Rapid draining of the battery may occur, necessitating repairs. Eventually, this part of the car will become ineffective, requiring replacement every 50,000 to 60,000 miles. While it may cost you some money, you'll need to invest in this upkeep to ensure your car remains operational.

The remote key for a 2017 Toyota Corolla cannot accept a CR2032 battery due to its thickness, as it will not fit properly. Instead, a CR2016 battery is the appropriate choice.
The appropriate battery is CR2016.
