Replacement Car Keys FAQ's
What is the cheapest way to get a new car key?
The most cost-effective method to obtain a replacement car key is through a professional auto locksmith. Auto locksmiths typically offer services that are both faster and more affordable than those provided by car dealerships. They possess the necessary equipment to cut and program keys for a wide range of vehicle makes and models. Additionally, many auto locksmiths offer mobile services, allowing them to come directly to your location. This convenience often results in quicker service and reduced costs compared to dealership options.
What if i lost my car key and no spare?
If you’ve lost your car key and don’t have a spare, it’s advisable to contact a local auto locksmith. They can create a new key for your vehicle, often more quickly and affordably than a dealership. Auto locksmiths have the tools and expertise to cut and program new keys on-site, and they can also deactivate the lost key to prevent unauthorized use. Before proceeding, it’s recommended to obtain quotes from multiple locksmiths to ensure you’re getting the best price.
Can you replace a car key battery by yourself?
Yes, replacing a car key fob battery is generally a straightforward process that you can do yourself. Most key fobs use standard lithium coin batteries, such as CR2032 or CR2025. To replace the battery, you’ll need to open the fob, which can often be done using your fingernail or a small flathead screwdriver. Once opened, you can identify the battery type, purchase a replacement, and install it. Detailed instructions are typically found in your vehicle’s owner manual. For a visual guide, you can refer to this tutorial:
How much does it cost to replace a car key battery?
The cost of replacing a car key fob battery is relatively low. Individual batteries typically range from £1 to £7, depending on the brand and retailer. For example, retailers like Halfords offer a variety of car key batteries within this price range. If you choose to have the battery professionally replaced, such as at a dealership or locksmith, there may be additional service charges. However, many find that purchasing the battery and replacing it themselves is both cost-effective and straightforward.
Can I drive my car with a dead key battery?
In most cases, a dead key fob battery will not prevent you from driving your car. Many vehicles are designed with backup systems to ensure functionality even when the key fob battery is depleted. For instance, some cars allow you to start the engine by holding the key fob close to the start button or placing it in a designated slot. It’s advisable to consult your vehicle’s owner manual for specific instructions related to your model.
