Frequently Asked Questions
1. How do I confirm I need the "0140" board?
You must open your current keyless entry remote and check the circuit board. It should have "0140" printed on it and lack any letter stamps like "E" or "G" near the buttons. Board versions are not cross-compatible.
2. Why is professional programming required for this push-to-start key?
Lexus smart proximity remote systems use encrypted frequencies that can only be synchronized via the OBD2 port using specialized diagnostic tools. This prevents unauthorized duplication.
3. Does this include the physical emergency blade?
Yes. This proximity key includes an uncut LXP90 emergency blade and a pre-installed CR1632 battery, making it ready for a locksmith to cut and program.
⚠️ Critical Compatibility Check
This remote is specifically for Board ID 0140. Even if your proximity key looks identical on the outside and has the same FCC ID, it will not work if the internal board ID differs. Always verify your internal board number before purchasing.
