To retrieve keys from a locked car without breaking the window, you can use a few methods. If you have a slim jim, carefully slide it between the weather stripping and the window to unlock the door by manipulating the latch. Alternatively, you might use a long, thin tool like a coat hanger to reach the unlock button or handle, depending on your car’s interior. For newer cars with electronic locks, you can try using a lockout tool kit, which often includes inflatable wedges and long-reach tools. If these methods are not successful, contacting a professional locksmith or roadside assistance is the safest option. They have specialized tools and techniques to unlock your car without causing damage.
