Can a key fob be programmed without visiting the dealership?

According to John Ibbotson, CR’s head technician, “If you have a car that was constructed within the previous five years, a new-car dealer will typically be your best chance when you need a replacement key fob.” This is because expensive programming equipment is needed.

We discovered from Audi and Subaru dealers that some key fobs won’t function with aftermarket key fobs, despite the temptation to go for a less expensive one online.

A service advisor at Hoffman Audi in East Hartford, Connecticut remarked, “If you want a new key fob for your Audi, it has to come from us.” The key fob has a built-in security chip that cannot be modified to work with another Audi. A new aftermarket Audi key fob cannot be purchased online because of the requirement for this chip. He claimed that “the fob has evolved into a crucial component of the security of the car.” We were informed that the typical cost of replacing an Audi key fob, including programming, is $500.

This applies to all European vehicles, not just Audi. Because the manufacturer can only program the digital key encryption in a small number of exclusive stores in North America, they nearly always require the customer to see a dealer, said Yu of CR.

Other merchants we contacted, such a Lexus dealership and a Chrysler/Jeep/Dodge dealership, stated they don’t mind attempting to program aftermarket fobs if the buyer requests it as long as the customer is aware of the dangers.

We were advised by a service advisor at a Lexus dealer that they were reluctant to work with aftermarket key fobs. If we try to program it and it doesn’t function, we still have to bill them for our efforts, we can’t warranty parts or labor.

Fortunately, even if you have to visit a dealer, the procedure is quick. Key-fob programming, according to the majority of the dealers we spoke with, usually only requires 15 to 30 minutes, and the entire process, including creating the mechanical replacement key, rarely lasts longer than an hour.

Even if they handle everything for you, going to the dealer doesn’t have to be expensive. Even with European brands, this held true. A replacement fob with a laser-cut key and programming for CR’s 2015 VW Jetta would cost roughly $225, according to a local Volkswagen dealer with whom we spoke.

Customers can save money on programming with some companies, like Chevrolet. For instance, a Chevrolet official informed us that the key-fob programming does not need to be done at the dealership and that General Motors key fobs are on the more affordable side ($147.98 for a 2019 Chevrolet Malibu with keyless entry, push-button start, and remote start).

The car must be present, he added. “The programming technique is explained in the vehicle owner’s manual.

Be advised that most customer-programmable key fobs, regardless of brand, require two active, functional keys in order to program a third new key without visiting the dealer, according to Yu.

What should I do if my key fob doesn’t work?

You won’t be able to use keyless entry or remote unlocking if your BMW has Comfort Access if the battery in your key fob has died. You can still enter and manually start your automobile, though.

Press and hold the key release button at the remote fob’s base while unlocking the door of your car, then slide out the internal key blade. This can be used in place of a standard key to unlock your car. You can locate a little hole on the bottom of the handle if the keyhole is hidden on your car door. Use the key blade to pry off the trim panel and expose the keyhole by inserting it into the hole.

Are new keys required to be programmed?

Transponder keys are more difficult to replace and should be handled with extra care to prevent loss since they are given a distinctive electronic code utilizing a carbon microchip installed within a particular glass container. However, a different transponder car key can be ordered and reprogrammed directly from the automaker by using a certified, bonded, and licensed locksmith like Altona Locksmiths.

When a transponder vehicle key’s microchip is recognized by the car’s on-board computers, the car can be opened and started. If the key’s unique code cannot be read, this can occasionally happen. Reprogramming of the automobile key is necessary when this occurs.

Most car owners don’t understand how crucial their transponder car key is until it stops working. These keys can sustain damage in a variety of ways, with water damage and physical damage being the most frequent, but you will need to get them reprogrammed if your car’s on-board computer cannot recognize the unique code on your key.
