Keystone FO2521123 Starter Relay Replacement

The Keystone FO2521123 is an OEM-style replacement starter relay engineered to restore proper starting system function. The starter relay serves as a critical electrical switch in the ignition circuit, receiving the low-current signal from the ignition switch and using it to close a high-current circuit that delivers battery power directly to the starter motor.

Key Features:

• OEM-style form, fit, and function for direct replacement
• Engineered to handle the high-current demands of the starter circuit
• Restores reliable engine cranking when the original relay fails or sticks
• Plug-and-play installation — no modification required
• Manufactured to meet original equipment specifications

A faulty starter relay is a common cause of no-crank or intermittent starting conditions. Replacing the relay with a quality OEM-style unit like the FO2521123 ensures dependable electrical contact and long service life. This part is sold individually and is designed for straightforward installation.
