I have the Forte locking skewers bought at Performance. I lost both "keys" or little wrenches. Any advice on how to remove the skewers without the key?? I can't seem to find anywhere to order another key & don't feel like buying a new set. Thanx

Do you have a Performance retail shop nearby? They could remove the skewer.

The manufacturer should be able to supply replacement keys. By the looks of them removal with a ViseGrip should be possible but they will suffer some damage. You might be able to grind down an ignition wrench to fit. If all else fails you can carefully cut the skewers off with an angle grinder and replace them.

It's not too clear exactly what type of locking skewers you are using, since 'forte'' is just a performance brand name and I dunno what design they are rebranding....

if your lost key is a simple allen with pin in center, a triangle, or a pentagon, just go to a good LBS, they tend to keep a few handy.

if your key is 'unique' such as PinHead skewers, then a sharp flathead screwdriver and a hammer against one of the dimples in the head can gradually unscrew it.

if the above ideas don't apply/work,
get a pair of cone wrenches 2x15mm for the front wheel, 2x 17mm for the back wheel; use them to overtighten the hub bearings, (this will be take muscle since you will be overpowering the cone/locknut friction interface)
overtightening will reduce the OLD(over locknut dimension) of the hub by a few mm; thus relieving the skewer tension so you can unscrew the skewers by hand and drop the wheels out of the frame
afterwards you will need to readjust the hub bearings
(this method defeats every locking skewer ive seen on market)

and of course, as stated already there are destructive removal options
via grinding/dremeling a gripable surface onto the locking nuts, cutting off, etc
