<p data-start="114" data-end="655">Car key replacement is needed when your key is lost, broken, or not working. There are different types of keys, such as normal metal keys, transponder keys with chips, remote fobs, and modern smart keys. The replacement cost depends on the type of key. Normal keys are cheap, but smart keys can be expensive. You can get a new key from a car dealer, a locksmith, or some online services. Locksmiths are usually faster and cheaper. Always keep a spare key with you. This will save time, money, and stress if you ever lose your main car key.
