Door Lock Actuator for BMW 7 Series, 12V DC Aluminum Motor Direct Fit Replacement
Meet the BMW 7 Series Door Lock Actuator — a robust 12V DC aluminum motor designed to restore reliable central locking in your BMW 7 Series. If your doors fail to lock consistently, won’t respond to the remote, or unlock intermittently, this replacement actuator offers a direct-fit solution that minimizes downtime and saves on dealership visits.
Built with a sturdy aluminum housing, this actuator is designed to withstand daily use and harsh conditions. It matches OEM references 73237820510 and 51217185689 for straightforward installation. This part replaces worn or faulty lock motors to restore strong locking torque and reliable remote operation, helping you keep your vehicle secure regardless of the weather or road conditions.
Designed for DIY or professional replacement, the motor is easy to swap thanks to accessible locking block assemblies that are fixed by screws. Replacing the motor or the lock block assembly can be a cost-effective way to renew function without replacing the entire door mechanism, saving you time and money.
Why replace? Common symptoms include remote lock failures, inconsistent locking, or the door being opened from the outside after attempting to lock. Replacing the motor renews performance and helps you maintain the security of your vehicle.
Benefits & Tips
- Restore consistent locking: eliminate intermittent lock engagement and remote lock failures for peace of mind.
- Cost-effective maintenance: swap just the motor or lock block assembly instead of the entire door hardware, reducing service costs.
