How To Replace Lexus Key

Getting a replacement for a vehicle key fob that has broken down can be expensive and time-consuming. If you drive a Lexus or another high-end car, the cost can be higher than you anticipate. Losing your key fob can also be an expensive mistake, but with enough preparation and information, none of these situations needs to be a major source of anxiety for you.

Start by examining the battery and button functionality of the key fob before considering replacement. If you’ve had your automobile for a while, a dead battery might only need to be replaced. Additionally, the buttons may become stuck or cease to operate due to normal wear and use. The simplest form of replacement is this one. The “guts” of your key fob can be swapped out for a newer model for less than $50 if you buy a replacement key fob shell from one of the many online retailers. Install a new battery at the same time; it will only cost you roughly $6. You can use your updated fob immediately.

If you believe the problem with your fob extends beyond normal wear and tear, you should contact your local Lexus dealer or a locksmith that is certified to provide new key and fob services. Both options need you to have your identification, vehicle registration, ownership documentation, and VIN on hand. Getting a full key fob replacement is just the start because luxury car brands are so technologically advanced. To program your fob and make sure it functions exactly as well as the original, you also need the correct help. The about $375 cost of each replacement key fob may be paid if you go via a dealership and your car is still covered by warranty. Consider hiring a locksmith if you’ve lost your key and are locked out. You can take advantage of their emergency service hours and the price may be slightly less than a dealership. Your insurer or a roadside assistance provider may be able to compensate you for their services.
