1. Contact a Lexus dealer. This is the most straightforward option, but it can also be the most expensive. The dealer will be able to cut and program a new key for your vehicle, and they may also have spare keys in stock.
2. Use a locksmith. A locksmith can also cut and program a new key for your vehicle. However, it's important to find a reputable locksmith, as some locksmiths may not have the necessary experience or equipment to properly program your key.
3. Order a key online. There are a number of websites that sell replacement keys for vehicles, including the 1999 Lexus RX-300. However, it's important to be careful when ordering a key online, as some websites may sell counterfeit or defective keys.
Here are some additional tips for getting a replacement key for your 1999 Lexus RX-300:
* Make sure you have the correct vehicle identification number (VIN) before you order a replacement key. The VIN is a 17-digit number that can be found on your vehicle's registration or insurance card.
* If you're ordering a key online, make sure you read the reviews of the website before you purchase a key.
* When you receive your replacement key, make sure you test it to make sure it works properly before you use it on your vehicle.
