Can You Drive With A Dead Key Fob

No auto manufacturer is going to pin everything on the key fob working all the time. Therefore, even if your battery dies, you can still use the fob to drive the car.
- Despite most cars going keyless, several of them still have a key slot usually located on the steering column. It will typically be covered by a plastic cover which you can pop off. Once you insert the physical key into it, you can easily turn on the car and drive away.
- Some cars begin ignition with the START button, which switches on the car only if the key is detected. With a dead battery, the car may not recognize the key fob and hence the START button may be unresponsive. In such cases, you can use the fob itself to push the START button, which will switch on the car.
- Some vehicles like Fords have a slot on the steering column where you can insert the fob, which will start the vehicle.

When To Go To A Dealer For A Replacement
If you have a car that was built within the last five years, a new-car dealer will usually be your best bet when you need a replacement key fob, due to the expensive programming equipment that is required, says John Ibbotson, CRs chief mechanic. Although it might be tempting to search for a cheaper key fob online, we learned from Audi and Subaru dealers that some won’t work with aftermarket key fobs.
If you want a new key fob for your Audi, it has to come from us, said a service adviser at Hoffman Audi of East Hartford, Conn. There’s a built-in security chip in the fob that cannot be reprogrammed for another Audi. The need for this chip is also why you can’t buy a new aftermarket Audi key fob online. The fob has become a critical part of the security of the car, he said. The average price for an Audi key fob replacement, including programming, is $500, we were told.
This isnt just the case for Audi, but European cars in general. They almost always force the customer to go to a dealer because the digital key encryption is only programmable by the manufacturer in a few select outlets in North America, says CRs Yu.
Other retailers we called, including a Chrysler/Jeep/Dodge dealership and a Lexus dealership, said they dont mind trying to program aftermarket fobs if thats what the customer wants them to do, as long as the customer understands the risks involved.
