Did you lose your car key? In the past, a quick trip to the hardware store might have solved your problem. But those days are fading as simple metal keys give way to key fobs.
These high-tech devices offer convenience like keyless entry and advanced security, but replacing them can be a whole different story. From navigating dealerships to exploring locksmith options, there's more to consider than a spare key at the ready.
If you're facing a key fob replacement and feeling lost, stick around! This guide will break down your options and help you get back on the road smoothly.
What is a Key Fob?
In simple terms, a key fob is a tiny remote control with an RFID chip and an antenna inside. It utilizes radio frequencies to communicate with another RFID tag inside a reader device, which is attached to a locking system.
Each car key fob chip is designed to transmit specific RFID tag information that matches what the reader device has been programmed to accept.
When you press the button, the key fob transmits an RFID signal to the reader device. If the RFID information transmitted from the key fob matches what the reader is programmed to accept, the system will open the car door.
These small handheld devices have been revolutionized for the development of keyless remote entry systems. Key fobs have truly become a very important piece in many people’s lifestyles.
Why Key Fobs Need Replacement
Just like simple car keys, fobs can be misplaced easily. They’re also not indestructible. Like any other technology, especially one that spends much of its life jousting around in pockets and purses, key fobs can eventually stop working.
Even though their plastic and metal shells are designed to handle a beating, key fobs are constantly being dropped, bounced, banged, and exposed to moisture and extreme temperatures. This is when you need a mobile key fob replacement.
How and Where You Can Get Your Car Key Fob Replaced
Key fobs that work just like factory units are available for many vehicles ranging from luxury cars like BMW key fobs to Mercedes key fobs to fobs for truck keys.
Although some manufacturers do offer generic universal key fobs, automotive locksmiths generally recommend against them. They suggest that it’s better to buy fobs that are made specifically for your car model so you can be sure they’ll work properly.
You should also buy from a reputable source for automotive key fobs, keys, and other locksmithing services instead of simply hunting for the least expensive option. By this, you’ll ultimately avoid the potential headache of getting a mismatched or poorly functioning fob.
It is also worth mentioning that not all vehicles can make use of aftermarket fobs. If your vehicle is one of them, you’ll likely have to head to the dealer.
Generally, if the fob is only available from the dealership it’s because the car key and fob replacement require technological and security expertise exclusive to the original manufacturer’s service department.
How to Program a Key Fob Replacement
When it comes to remote car key replacement, it’s important to understand the key fob programming. And if you’re searching for “Car key programming near me” this section might be helpful for you.
Some replacement units, generally those for older car models with less sophisticated security systems — can be programmed by the consumer with relative ease.
This self-programming method usually involves some simple and repeatable steps. However, it’s important to note that often you’ll need at least one and sometimes two functional keys to program a replacement.
Other key fob replacements can only programmed by a dealership. Again, as discussed above, this is generally because of the security features and software systems used in late-model vehicles.
Professional locksmiths with expertise in automotive keys can program many fob replacements, and in certain cases will use software designed specifically for vehicle security systems and key fob programming. In fact, some dealerships even outsource their fob replacement services to locksmiths.
How Much Does Car Key Fob Replacement Cost
The cost of key fob replacement depends on several factors. Such as if your car fob is more mechanically complex then it will be more expensive to replace.
However, in most cases, car key fob replacement in India will cost you somewhere between ₹1500 (for mechanical key fobs)-and ₹35,000 (for remote key fobs and premium car fobs).
There are also key fobs that perform a wider range of functions or are part of smart security systems. The fobs include features like keyless entry, push-button start, remort start, or similar functions that fall into the “smart key” category.
You could end up spending around ₹35,000 for a replacement fob with all of this functionality. At the very high end are fobs that include an LCD display, such as those for some high-end BMWs and Mercedes. Key fob replacements for these units can soar into a high range of prices.
Use Spare Keys and Apps to the Rescue
Many automotive key fobs that don’t include a switchblade key come with a small metal key embedded in them that’s meant to be used if the fob fails.
This key slides in and out of the fob. It can be used to open doors and to start the car using a physical ignition lock that's usually tucked below the engine start/stop button on the steering column or in the center console.
It's also worth mentioning that even a key fob with a dead battery can sometimes be used to start a car. Pressing the ignition button with the dead fob instead of your finger can occasionally transmit enough of a signal to activate the security circuits and start the engine.
Some automobiles go one step beyond key fobs and offer mobile apps for your phone that can open door locks and start the ignition. Aftermarket apps are available for several vehicle models that don't come with one from the manufacturer.
In case something unexpected happens and you lose your fob, this software may let you use your phone to maintain access to and use your vehicle while you work on getting your key fob replaced.
