Product Overview
Operators often buy spare keys after one is lost, bent, worn smooth, or shared across a fleet. A new key can solve a worn-key problem, but it will not repair a seized, broken, or electrically failed ignition switch.
The keys operate compatible mechanical Deere lock cylinders and ignition switches. They are not electronic transponder keys and model listings are only useful when the existing lock uses this key code.
Compare RE183935 or RE71557, blade profile, shoulder position, head shape, machine generation, and existing key. Test gently; never force a key into a corroded cylinder.

Frequently Asked Questions
Q: Will this key start every John Deere tractor? A: No. Deere uses multiple key profiles and security systems. Match the existing key and reference.
Q: Does it need programming? A: This is a mechanical key set, not a transponder-programming service.
Q: What if the old key turns but the tractor will not crank? A: The fault may be in the switch, battery, relay, safety interlock, starter, or wiring.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
