Avoid dropping: Frequent drops on concrete can dislodge the small transponder coil inside the case. Modification the battery promptly: If the Laguna features the hands-free entry system (where the car unlocks as you approach), a passing away CR2025 or CR2032 battery can simulate a failing cardkey. Replace the battery every 1-- 2 years. Frequently Asked Questions Can I program a pre-owned Laguna cardkey from a junkyard?
