**Damaged key:**

A car key can be damaged without really being broken. The pattern and grooves on the key that fit with the lock on your car may have changed as a result of wear and tear or bending. The pattern and grooves on the key may get distorted by improper handling and maintenance combined with repeated use, which will impair its functionality.

**Dented Locking System:**

Your automobile's locking mechanism could be the cause of your car key's malfunction. After extensive use, the mechanism may have become worn down and stopped responding to your car key. When your key stops working due to a broken locking mechanism, you will only be able to get going by using a reliable car key replacement service.

**Damaged Key Fob:**

When using a keyless entry remote, there won't be any connection if either the transmitter or receiver, or the internal electronics of your automobile, are broken. Simple events like dropping, being exposed to extreme heat, and soaking in water, among others, can cause damage to the key fob.
