❓ Frequently Asked Questions (FAQ)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Q1: Why are there two different blade lengths for Lexus?
A: Early Lexus models (LS/SC) used a longer 50mm blade (TOY40), while later models (ES/RX) used a shorter blade (TOY48). This is the long version.
Q2: Can I program this key myself?
A: No. 4C chip keys require specialized diagnostic tools or cloning machines. On-board (manual) programming is not available for these Lexus models.
Q3: Is this an OEM Lexus key?
A: No, this is a premium aftermarket replacement key. It provides the same security and functional performance as the original at a lower wholesale cost.
Q4: Do I need to cut the key?
A: Yes. The blade is delivered uncut and must be cut to fit your vehicle's physical locks.
Q5: Will this work for my 1999 Lexus LS400?
A: Yes, most 1999 LS400 models use the TOY40 long blade and 4C chip provided in this listing.
Q6: What is a 4C chip?
A: The 4C was the first transponder chip used by Toyota/Lexus. It is a "Fixed Code" chip, which is less complex than the later "Rolling Code" chips.
Q7: How fast is shipping?
A: We process orders in 1-3 business days. Domestic shipping within the US typically takes 3-7 business days.
