When dealing with car lock issues, a common question arises: should you rekey or replace the locks? Both options serve the purpose of enhancing vehicle security but come with distinct processes, costs, and benefits. This comprehensive guide will help you make an informed decision based on your specific circumstances.
Top methods to rekey a car door lock.
What Does Rekeying a Car Lock Entail?
Rekeying involves changing the internal mechanism of the lock so that it works with a new key while rendering the old key useless. A locksmith accomplishes this by rearranging the pins or tumblers within the lock cylinder. This process is quick and cost-effective, especially when the lock itself is in good condition.
Rekeying is an excellent choice if you’ve lost a key, want to prevent someone with an old key from accessing your car, or have purchased a used vehicle and need to enhance its security. Since it doesn’t require replacing the entire lock, it’s also environmentally friendly and less expensive than a replacement.
What Does Replacing a Car Lock Involve?
Replacing a car lock means removing the existing lock and installing a completely new one. This option is necessary if the lock is damaged, corroded, or no longer functioning properly. Lock replacement also allows you to upgrade to more advanced or modern locking mechanisms, such as keyless entry systems or smart locks.
While replacement provides a brand-new lock system, it is generally more expensive and time-consuming than rekeying. It may also require replacing multiple locks in the car (doors, ignition, trunk) to ensure a unified locking system.
Key Factors to Consider
1. Condition of the Lock
- Rekeying is viable if the lock mechanism is still in good working order.
- Replacement is necessary for worn-out or damaged locks.
2. Security Needs
- Rekeying is ideal for security updates, like after losing a key or purchasing a pre-owned car.
- Replacing locks is better when you need advanced features or an entirely new system.
3. Cost
- Rekeying is usually cheaper since it involves fewer materials and labor.
- Replacement incurs higher costs due to parts and potential reprogramming of electronic components.
4. Convenience
- Rekeying is a faster process and can often be done on-site by a locksmith.
- Replacing locks may require more time, especially if parts need to be ordered.
