Manufacturer Equivalents / Cross-References

This LOCKGENICS replacement key is functionally equivalent to aftermarket and OEM parts replacing:

• Subaru OEM Part Numbers: 57497-AL00A, 57497-FJ021, 57497-FJ020, 57497-FJ230 (and similar G-Chip variants)
• Chip & Remote Spec: Same FCC ID (CWTWB1U811), G-Chip transponder, 315 MHz frequency
• IC: 1788D-FWB1U811 compatible chips used by many aftermarket suppliers

Important Notes

• Uncut & Unprogrammed: This key is supplied uncut and requires key cutting and remote programming by a professional locksmith or dealer.
• Programming Tools: Some locksmith tools (e.g., Smart Pro, Lonsdor, Zed-Full) may be required to pull PIN codes and program immobilizer functions.
• Verify Fit: Always confirm FCC ID, button layout, and frequency before purchasing — incorrect remotes may not program to your vehicle.
• Battery: Remote comes without battery installed — CR1620 or CR2032 commonly used (verify before installation).
• Not OEM: This is an aftermarket replacement by LOCKGENICS — programming acceptance depends on vehicle and programming tool support.

Note: This only works for older Subaru models (2014 and earlier) or in cases where the programmer requests a key code. After programming, it may take up to 2 hours for the remote to sync. For faster synchronization, disconnect the battery temporarily.
