No, the SUB4-PT transponder key is not compatible with a 2011 Subaru Forester.
The SUB4-PT is an older-style Subaru key with the SUB1 keyway (a traditional milled/double-sided cut), and it fits Subaru models from approximately 2005 through 2008–2009 (depending on the model).
The 2011 Forester uses a high-security laser-cut key with the DAT17 keyway, commonly referenced as the DAT17T13. While both keys share the same Texas Instruments 4D62 transponder chip, the blade keyways are completely different, so the SUB4-PT will not physically fit into the ignition of a 2011 Forester.
What you actually need for a 2011 Subaru Forester:
- A DAT17T13 transponder key (high-security laser-cut, 4D62 chip)
