We are flat towing a Chevy Spark with manual transmision. When towing you hardly know it is back there. My only problem is leaving the key in the ignition turned on so the steering is unlocked. I forgot to start it during pit stops and had a dead battery. Is there a fuse to pull???Or better still has anyone disabled the steering wheel lock so you don't need to insert the key?

Doesn't owner manual tell you which fuse(s) to pull?Many will suggest running a "charge line" from coach to toad battery.There's also a commercial version of a charge device.

Owners manual for our Malibu tells you which fuse to pull. On an auto trans the key allows you to take the trans out of park, there is no lock on the steering wheel.

Have a friend that had the same issue, called GM (several times) can got conflicting answers.I don't recall what the solution was, I will poke and see if I can get a response.

I have a Hyundai Elantra GT which requires the ignition to be in the ACC position for the electric power steering. The solution was to run a charge line. My motor-home already had power to the 7 pin plug so the tech just wired the car from the car receptacle to the battery. No problems at all in a years worth of towing.

We tow a 2013 Chevy Spark with a manual transmission. You need the key to be turned to unlock the wheels.There is NO FUSE to pull for this car. We have spoken directly to Chevy about it.We bought a battery disconnect switch and it is working perfectly. We disconnect the battery when we hook up and reconnect it when we disconnect the toad.Hope this helps.

Wouldn't be easier to put a quick disconnect on the battery so it wouldn't drain the battery

The brake tail and turn signal run are powered by the coach.

Check to see what actually makes the wheel lock, if it does at all.

On my manual transmission Fit, the lock is not activated until the key is pulled out, so I can leave the key in the "off" position. Same for my manual transmission truck.

It is more towable automatics that have the key problem, i.e. switch must be turned to an "on" position to get the selector out of Park.

Can't do that with the Spark. We tried it.

Chevy's directions are to put the car in neutral, release the hand brake and turn the key to accessory. There are no other instructions.

Strange thing is that we towed well over a thousand miles running all day and never had a problem. The dead battery problem just popped up one day and remained. I think there is some kind of phantom load running which we can't find. It's not worth tracing the entire electrical system, pulling fuses, etc to find it. The battery disconnect suggested by Chevrolet works perfectly and really isn't any bother.

The battery disconnect was the suggestion of Chevrolet. This simple and very inexpensive method ($10-$20 at an auto parts store, easily installed in 10 minutes) will not void any warranty on the car.

The battery disconnect works perfectly, was inexpensive, easy to install and solved the problem. Why would anyone want to start with running charge lines or disabling the steering lock?

Sounds to me like the quick DIY solution is battery disconnect.
Next, a little more complicated, charge line.
More invasive, modify steering lock.

Charge line is the one I would consider in this case.

The locking feature of many ignition switches can be disabled - allowing the steering wheel to turn without the key. A good (non-dealer) repair shop could tell the OP if this can be done to the Spark's ignition cylinder. From what I've read in the past it takes about half an hour to complete the procedure.

It may very well void any warranties, so keep that in mind as well.
