| This guided will help anyone to replace a battery in 8 easy steps! |
| If you are having issues unlocking your 2021 Toyota Venza using the vehicle-provided fob, the vehicle's fob needs a battery replacement. This guide will show you step-by-step how to replace the battery. |
|
| The fob that comes with the Venza comes with a battery identified as CR2450. Over time, the battery runs out due to prolonged use. If you start to notice that the remote doesn't respond or you have to press its buttons multiple times to get the vehicle to respond, your remote needs a battery replacement. |
|
| If the remote stops responding and you do not have a CR2450 battery, you can still unlock the car using the key inside the fob, as shown in Step 2. |
