Before Installing a Product - If you decide to install any products sold by Shark Electronics on this website, you must review the most current Product Guide, Installation Guide, User Guide, Owner’s Manual and any other vehicle-specific notes available on the manufacturer’s website. You are solely responsible for determining if you have sufficient technical knowledge of your vehicle’s systems to avoid installation errors that damage expensive vehicle components.
Damages - Shark Electronics is not responsible for any damage whatsoever caused by an installer to a user’s vehicle, including but not limited to any direct, consequential or incidental damages, damages for loss of time, earnings, business, profits, economic opportunity and the like that may result from the use, misuse, improper installation or operation of its products.
Shark Electronics is not responsible for any damage arising from or caused by a self-installer to the product or the vehicle, including any direct or consequential damages whatsoever. By performing a self-installation of any product purchased from us, the user releases Shark Electronics from any claims for damages it may have or may arise as a result of the self-installation.
Flashing Firmware - We can program your module before shipping if only one-step flashing is required. Enter your vehicle information during checkout (MAKE-YEAR-MODEL PTS/STANDARD-KEY GAS/DIESEL/HYBRID AUTOMATIC/MANUAL).
Compatibility - Product compatibility is always subject to change. Check the manufacturer’s website for the most up-to-date firmware, installation manual and vehicle-specific details. We try to provide the most up-to-date compatibility by including direct links to the product page.
Range - The remote range is based on the line-of-sight unobstructed testing under ideal conditions. The actual range will vary due to local conditions including, but not limited to, environment, terrain, physical obstructions, vehicle location and orientation, interference and other possible impediments.
Website Navigation - You will find most of the listed products using the main menu. Our instant search box is the shortest way to reach an item if you already know the product name, model, or SKU. If the product is not in the drop-down list, just hit enter, and the refined search page will open. Here you have multiple options to filter your search.

Shipping Cost - With shipping costs increasing every year by 3-4% and us wanting to keep our product prices accurate and not inflated by "Free Shipping," we offer you the best live shipping rates at checkout. If the live shipping rate changes significantly between the time you placed your order and when we printed the shipping label, we will refund you the difference. If we can find a comparable service (same transit time) available at a lower rate, we may use a different Currier and refund you the difference.
