Will this work if the 2021 Land Rover Discovery has an aftermarket alarm?

Will this work for older 2021 Land Rover Discoverys? Mine's a 2009.

🔑 Car Key & Fob FAQ

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

Security Systems
Some systems reset by: 1) Disconnecting battery for 15+ minutes 2) Using original keys in specific sequences 3) Professional diagnostic reset. Consult your manual - procedures vary. Persistent issues may require dealer-level tools.
Key Tip: Consider key insurance for expensive smart keys
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.
Cost & Options
1) Always have at least 2 working keys 2) Get spares made before losing originals 3) Consider key insurance/add-on coverage 4) Store key codes safely 5) Use protective cases for smart keys 6) Program new keys before old ones fail completely.
Key Fob Issues
1) Find the seam and pry open the fob (some have tiny screws) 2) Note battery orientation 3) Remove old battery (CR2032 is most common) 4) Insert new battery 5) Reassemble. Test all buttons - if issues remain, the fob may need reprogramming.
Key Tip: Avoid exposing key fobs to water or extreme temperatures
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.
Key Tip: Newer cars often require dealer programming for first key replacement
Key Fact: Some insurance policies offer key replacement coverage
