Keys and Locks

The keys and locks of an MX5 NB (1998–2000) are used daily and serve as the link between the driver and various parts of the car. The system consists of cylinders, latches, keys, and mechanical parts that ensure the doors, trunk lid, and ignition switch function properly. After years of use, locks can become stiffer due to wear, dirt, or aged lubricant, making them less smooth to operate. Because door locks are directly integrated into the moving parts and locking mechanisms of the doors, the fit and condition of these components greatly affect ease of use. Especially in older cars, you’ll notice that a properly functioning locking system directly contributes to a solid and well-maintained impression.
