It's is not a good idea. With only 4 bolts out of 5, the stress on the remaining bolts will eventually snap another one. It may also snap off all of them at once. Hit a pothole, a dip in th road, or just run over something and the wheel could come right off the car. You may have some shaking while driving because the balance will be off. Just go to a local auto parts dealer and get a new wheel bolt(less than $3). When you do buy one, ask for a wheel stud, because thats what they are actually called. As for the wheel lock, just buy a new set. It's less of a hassle than trying to get the broken bolt out of the one lock. The wheel studs are not that hard to replace. Use a hammer and a bolt that is just a little smaller in diameter than the stock wheel stud to knock the broken stud out of the hub. Then install the new wheel stud into the hub, place a few washers onto the new stud(where the rim would mount), put one of the lug nuts on the new stud. Use a good combination wrench to tighten the nut untill the new wheel stud fully seats into the hub. Just use the other 4 as a visual example of how it should look. After the wheel stud is fully seated remove the wheel nut and washers, then mount the rim and torque everything back to spec. It'll take some muscle to fully seat the wheel stud, but the whole process shouldn't take more than a 30min. to complete if you have all the parts and tools ready.
