Any updates on getting the key code for the Lotus Exige S?

Waiting to see if this will work on my Lotus Exige S as well.

Can’t believe this worked on my Lotus Exige S. Huge thanks!

This trick worked for my buddy's Lotus Exige S. Giving it a go myself.

Trying to reprogram a new key for my Lotus Exige S—need the code first.

I’m also looking for how to retrieve the key code on a Lotus Exige S.

🔑 Car Key & Fob FAQ

Common questions about key programming, fob issues, and replacement options

Lost Keys
Locksmiths or dealers can: 1) Decode your door or ignition lock to determine key cuts 2) Access your car's key code through manufacturer databases (with proof of ownership) 3) Program new transponder keys using diagnostic equipment.
Cost & Options
Quality aftermarket keys work well for most vehicles at lower cost. However, some luxury brands use proprietary technology only available through dealers. For expensive cars, OEM may be worth the extra cost for reliability.
Key Tip: Keep spare keys in a faraday bag to prevent signal amplification theft
Key Fob Issues
This typically indicates: weak fob battery (replace first), damaged fob antenna, or issues with your car's receiver (often in the door handle or rearview mirror). Environmental interference from other electronics can also reduce range.
Key Tip: Avoid exposing key fobs to water or extreme temperatures
Cost & Options
You can buy fobs online, but: 1) Must match your exact model/year 2) Many still require professional programming 3) Cheap knockoffs may not work reliably. Some eBay/Amazon sellers offer programming instructions for DIY-friendly models.
Key Tip: Newer cars often require dealer programming for first key replacement
Security Systems
This means your car's immobilizer system can't read the key's transponder. Causes: dead key battery, damaged transponder chip, faulty car antenna ring around ignition, or system needs resetting. Try replacing the battery first.
Key Fact: Some insurance policies offer key replacement coverage
