Oh no—mistakes happen! You won’t be able to fix a snapped car key, but you can replace the key.
It may be tempting to glue the key back together or perform a similar DIY repair, but you should avoid at-home repairs because they can cause even more damage, especially if the key gets stuck in your lock or transmission.
Rather than repair the key, you should visit a dealership or locksmith, and bring the broken key with you. Typically, a car key costs $100 to $200 to replace and can be ready in a few hours. However, the cost varies depending on your vehicle’s make and model. Some keys may cost as little as $50 and others upwards of $500.
